How To Choose Custom Aluminum Extrusions

Click to ExpandHow-To-Choose-Custom-Aluminum-Extrusions

Initially developed to shape fluid forms in processing raw material, extrusion became one of the most advanced processes in which aluminum is formed into different shapes and sizes. Extruded aluminum offers various advantages for parts and products. For instance, it features natural anti-corrosive properties that can be further enhanced through anodizing and other finishing processes.

This article aims to help manufacturers who fabricate and use their own parts and components maximize the power of aluminum extrusion design.

Factors To Consider in Aluminum Extrusion

The surface-to-volume ratio of aluminum significantly changes throughout the extrusion process. This is achieved by applying compressive forces to the billet using rams, punches, tools, and dies.

Here are the top factors to consider to manipulate aluminum to create more durable and high-quality extruded components:

Type of Extrusion Process

There are two types of extrusion processes: direct and indirect. Direct extrusion is when the ram and the metal flow in the same direction; indirect extrusion is the opposite. A reliable aluminum extrusion provider can easily differentiate which of the two types is advantageous for fabricating a specific component.

Extrusion Pressure

The pressure needed to start metal flowing and reduce friction at the interfaces between the billet, die, and the chamber is exceeded by the extrusion pressure. It varies between 800 MPa and 1200 MPa.


In custom aluminum extrusion, friction between the billet and die, or chamber and die, is crucial. To manage the metal flow and lower the amount of power needed for compression, friction is removed or minimized.

Die Type and Design

The elements that form the metal are called dies, and their designs dictate the mechanical operation of the metal during extrusion. Dies for extrusion can be solid, semi-hollow, or hollow.


Extruding high-strength aluminum alloys calls for lubrication to help the metal as it is distorted as the die and the billet slides up against the chamber. Lubricants used for the process are a mixture of glass powder, graphite, and oil.

Types of Aluminum Alloys

Different aluminum alloys call for various extrusion settings, as aluminum alloys are categorized into series according to the primary alloying element. For instance, Alloy 6063 and Alloy 6061 are popular material choices for extruding aluminum alloys because they provide a high-quality finish.


Extruding aluminum in high temperatures — between 375 °C (705 °F) and 500 °C (932 °F) — is known as “hot extrusion.” High temperatures improve the flow of the metal, resulting in flawless extrudates. However, high-temperature extrusion can be disadvantageous in some applications. Thus, you must work with a manufacturing partner who can advise on the best techniques per project.

Extrusion Ratio

The billet and die opening cross-sectional area ratio defines the extrusion ratio. Larger deformation results from a higher extrusion ratio. Therefore, a higher pressure must be applied to the aluminum material to decrease the ratio.

Extrusion Speed

Extrusion speed is defined as how quickly metal passes through the die. The extrusion speed should be balanced to keep the metal at the proper temperature. For example, high extrusion pressures are needed for faster extrusion speeds, which raise exit temperatures. On the other hand, slower speeds give the temperature plenty of opportunity to flow and disperse.

Billet Length

The length, shape, and extrusion ratio of the extrudate are constrained for a given billet diameter by the billet length. Additionally, the billet length impacts the necessary extrusion pressure, as the needed extrusion pressure increases with billet length.

Golden Gate Bridge

Click to ExpandGolden Gate Bridge” data-lazy-src=

Since 2021, residents near the Golden Gate Bridge in San Francisco, California, have been complaining about a strange humming sound emanating from the world-famous bridge. This peculiar noise is often heard when winds hit the newly-installed railing slats on the west sidewalk from a slightly off-kilter slant.

The said railing slats were initially established to protect the bridge from damages caused by sustained high winds of up to 100 mph. Engineers have installed these to prevent the Golden Gate Bridge from experiencing the same unfortunate fate as Washington’s Tacoma Narrows Bridge, which collapsed in 1940 — shortly after it was built — due to strong winds.

Existing Structural Specifications

Golden Gate Bridge could originally withstand a maximum of 69.34 mph sustained wind speed. However, it had been repetitively shut down due to powerful winds gusting from 69 mph to 75 mph in 1951, 1982, and 1983. While there has been no damage in the past 84 years, engineers developed new railing systems to help the Golden Gate Bridge endure a maximum of 100 mph wind speed, which is estimated to happen every 10,000 years.

However, since residents have been complaining about the humming sound from the bridge, the Golden Gate Bridge District is implementing new designs to minimize the sound from the bridge’s vibration by 75%. Richardson Metals is working with the Golden Gate Project team to develop solutions to reduce or eradicate the sounds that occur during high wind events with our aluminum extrusion.

Proposed Design

To eliminate the Golden Gate Bridge’s humming sound, engineers and leading bridge aerodynamics and acoustics experts have proposed to install thin, U-shaped clips affixed to both edges of all 12,000 vertical slats on the west railing. Thin rubbers will be inserted in these 1/8” thick 6061 aluminum extrusion clips to dampen the vibrations contributing to the bridge’s sound.

Through these clips, “vortex shredding” — the result of small vibrations in the air — will be minimized as they will lightly disrupt airflow as it passes over each slat. In addition, the clips will cover the slats from top to bottom and be painted in the Golden Gate Bridge’s famous International Orange to make it invisible to most bridge users.

Engineers and bridge experts guarantee that this new installation will not negatively impact Golen Gate Bridge’s architecture. The project is expected to be complete by the end of 2022.

Temper Designations for Aluminum


Aluminum is popular for various applications due to its lightweight, strength, and corrosion resistance. The mechanical properties of aluminum can be altered using several processes, including work hardening and adding alloying elements; however, one of the most common ways of altering certain grades of aluminum is through tempering.

Since the tempering process can have such a significant effect on aluminum alloys, it’s crucial to understand the various aluminum temper designations and what they mean. This is critical in ensuring you choose the correct material and preventing failures or fractures.

What Are Temper Designations for Aluminum?

Aluminum temper designations denote the tempering treatment of aluminum using a string of alphanumeric characters. The marking follows the alloy designation and a dash, such as 6061-T6, indicating the aluminum alloy “6061,” followed by the tempering designation “T6”. When searching for an application-specific material, it is critical to determine the temper designation. Aluminum tempering is indicated by the following primary designations:

  • H: Strain hardened
  • T: Thermally treated
  • F: As fabricated
  • O: Annealed

The number that follows the letter indicates how the manufacturer performed the tempering treatment. For example, T5 and T6 are both thermally treated, but T5 means that the alloy was cooled from a high-heat shaping process and then artificially aged, whereas T6 means it was solution heat treated before being artificially aged.

Importance of Temper Designations for Aluminum

Variations in the temper designation inform purchasers about nuances that could significantly affect the alloy’s mechanical properties. The temper of certain alloys can impact the appearance of aluminum after anodizing as well as maximize the mechanical properties of heat-treatable alloys. Many standardizing agencies list the specifications of aluminum casting alloys, but the numbers may not correlate across agencies.

Common Aluminum Temper Designation Applications

Several aluminum alloys and temper designations are prevalent throughout various industries. The following temper designation and aluminum alloy combinations are popular in many applications:

  • 2024-T4: Screw machine products, wheels, hardware, fasteners, and aircraft structures
  • 3003-H14: Pipes, pressure vessels, litho sheet, trim, tanks, and equipment for food and chemical handling
  • 5052-H32: Rivets, wire, lighting, appliances, transportation, fuel tanks, and oil and fuel lines in aircraft
  • 6061-T6: Valve parts, valves, appliance fittings, hydraulic pistons, brake pistons, magneto parts, hinge pins, general and decorative hardware, electrical connectors and fittings, marine hardware and fittings, couplings, camera lens mounts, and aircraft fittings
  • 6063-T5: Transportation, irrigation pipes, architectural extrusions, furniture, railings, and pipes
  • 7075-T6: ATV sprockets, defense and aerospace parts, aircraft, keys, worm gears, regulating valve components, missile parts, gears and meter shafts, fuse parts, shafts, and aircraft fittings

Guide to 6061 Aluminum

Click to Expand6061 Aluminum

One of the most important considerations when designing an industrial project is the materials involved. With metal alloys, it can be challenging to select the best option because there are so many.

Aluminum is a popular material for a wide range of industrial projects, with an equally vast range of alloys. Aluminum 6061 is one of the most versatile and durable alloys in use today. This guide will discuss the properties, benefits, applications, and types of aluminum 6061 that make it such a highly preferred material.

What Is Aluminum 6061?

Aluminum 6061, or 6061 aluminum, is the world’s most commonly used aluminum alloy. Its primary alloying elements are magnesium and silicon. Aluminum 6061’s heat treatability, easy machining, weldability, corrosion resistance, and strength are desirable properties for many applications. This alloy is also excellent for situations that require anodization, which adds a coating of anodic oxide to protect the metal.

Aluminum 6061 is commonly found in consumer products—bicycle frames, cameras, pins—as well as industrial products like marine hardware, decorative hardware, aircraft parts, couplings, electrical components, valves, and brake and hydraulic pistons.

Aluminum 6061 Benefits and Applications

Aluminum 6061 is also called structural aluminum for its strength in structural applications. Because it is a wrought alloy instead of a cast alloy, it possesses good mechanical properties that allow it to be rolled or forged into various standard and custom shapes. Anodization can add aesthetics, durability, and corrosion resistance to the metal surface.

The adaptability of 6061 aluminum has made it a standard material in these industries:

  • Construction
  • Sports and recreation
  • Medical
  • Electronics
  • Telecommunications
  • Aerospace
  • Military

General Properties of 6061 and Common Types of 6061

Pure metals have fixed, limited properties, but aluminum 6061—an alloy of aluminum, magnesium, and silicon—combines the best properties of each element to produce a better metal. Magnesium increases strength, and silicon lowers the metal’s melting point. The hybrid material is stronger and more flexible, and it can be further adjusted to specific needs. The distinct elements of aluminum 6061 cannot be separated, giving it a strength that rivals steel.

There are two main tempers of 6061 aluminum: 6061-T4 and 6061-T6. Aluminum 6061-T4 is aged naturally, whereas aluminum 6061-T6 is aged artificially to enhance its strength.

All 6061 aluminum products have good corrosion resistance, machinability, weldability, and general workability. It is a medium to high strength metal alloy.

This guide will outline 6063 aluminum’s features, applications, benefits, and types to help you determine if this metal is the best material for your application.

What Is Aluminum 6063?

Click to Expand A-Guide-to-6063-Aluminum

Aluminum 6063, or 6063 aluminum, is a heat-treatable 6000 series alloy comprised of aluminum, magnesium, and silicon. Often called architectural aluminum, 6063 aluminum is often soft anodized to create colored, visually appealing architectural structures.

Aluminum 6063 Benefits and Applications

6063 aluminum is known for its excellent corrosion resistance against both chemicals and stress cracking. The alloy is easily welded and machined. Specifically, aluminum 6063 is a preferred material for long structural pieces with a constant cross-section, such as pipes, tubes, angles, and “U” or “L” shaped channels.

6063 aluminum is ideal for architectural applications. Some of the most common applications include:

  • Sign frames
  • Door frames
  • Window frames
  • Truck frames and trailers
  • Railings
  • Balustrading
  • Irrigation tubing
  • Roofing
  • Shop fittings
  • Extrusions

General Properties of 6063 and Common Types of 6063

Aluminum 6063 is a preferred material for extrusion because it can be easily pushed through dies to fit various cross-sectional shapes. As an alloy of aluminum, magnesium, and silicon—with trace amounts of iron, copper, manganese, and other elements—6063 aluminum is tough, flexible, workable, and corrosion-resistant. In fact, aluminum 6063 outperforms aluminum 6061 in corrosion resistance.

6063 aluminum comes in two variations: 6063-T4 and 6063-T6. They have similar physical compositions, but their mechanical properties differ due to contrasting tempering methods. Aluminum 6063-T4 is aged naturally, while 6063-T6 is aged artificially to boost strength.

Outlining the Aluminum Extrusion Process

At Richardson Metals, Inc., we’ve provided aluminum extrusions to customers in a wide range of industries for over 40 years. This extensive experience allows us to create extrusions from a variety of grades in different shapes, sizes, and volumes. If you’re wondering how we bring your ideas to reality, read on. Below, we outline the aluminum extrusion process to illustrate how we turn raw aluminum material into finished parts and products.

What Is Aluminum Extrusion?

Aluminum extrusion is a manufacturing process that creates aluminum components with fixed cross-sections. The aluminum billet is first softened and then pushed through a steel die with the desired cross-sectional profile. After the material exits the die, it is cut and cooled into individual long lengths, each of which has the same shape and size depending on the component design.

The next section outlines the full list of process steps in further detail.

Click to ExpandAluminum Extrusion Process

Aluminum Extrusion Process Steps

The aluminum extrusion process consists of numerous steps:

  1. Die design. Before an aluminum extrusion operation can begin, the part or product designer must create the design for the desired component. This design determines the design of the die and if it can be extruded.
  2. Die creation. Once the component design and die design are approved, the die can be manufactured and
  3. Die preheating. Once the order is ready to run and the die is ready, it is preheated to support the flow of the metal through the die and placed in the extrusion press.
  4. Aluminum cutting. Once the die is prepared and positioned properly, solid and cylindrical pieces (i.e., billets) are cut from a larger piece of raw material.
  5. Billet preheating. The billets are preheated to approximately 900 degrees to improve their malleability.
  6. Billet loading. The preheated billets are transferred and loaded to the extrusion press.
  7. The extrusion ram applies pressure to the billet, forcing it into the container of the extrusion press and through the extrusion die. The amount of pressure applied depends on the extrusion design.
  8. Gas introduction. Aluminum extrusions are susceptible to oxidation. Introducing nitrogen into the die during operations creates an inert environment that reduces the risk of oxide formation. In its liquid form, nitrogen also helps cool the die, extending its service life.
  9. Emerging onto the run-out table. As the extrusion emerges from the die opening, it is guided onto the run-out table.
  10. Initial cooling. As the extrusion moves across the run-out table, a water bath or overhead fans help cool it.
  11. Initial extrusion cutting. After the extrusion partially cools and reaches the full table length, a hot saw separates it from the rest of the material.
  12. Final cooling. The individual extrusion is moved from the run-out table to a cooling table where it can cool to room temperature.
  13. Stretching. Throughout the process, the extrusion naturally experiences some twisting. This issue can be corrected by stretching it until it is fully straight and up to spec.
  14. Final extrusion cutting. Once the extrusion meets the shape specifications, the material can ship in long lengths or can be transferred to a precision saw to cut shorter mult lengths or finished part length.
  15. Aging. If needed, the individual extruded pieces then move to an aging oven where they are aged to the proper temper.
  16. Additional improvements. If needed, the extrusions can be subjected to further fabrication, machining, finishing, and treatment operations to improve or enhance their properties and/or achieve the desired dimensions.
