Aluminum Grades Used in Extrusion

Release time:2022-10-06

When designing an aluminum extrusion, you must consider how the material's unique qualities may influence or improve the final product. Aluminum extrusions can be used for various automotive and industrial applications due to their strength, low weight, and durability. While the metal's overall qualities reflect its adaptability, the variations amongst aluminum alloy grades are worth noting.

Choosing the appropriate grade of aluminum for your extrusions is one way to guarantee that your design will hold up to the rigorous conditions of its intended use. 

What is Aluminum Grade?


An aluminum extrusion alloy is a metal that consists of a specific ratio of one or more metals combined with aluminum. Examples of these metals are but are not limited to; copper, silicon, magnesium, and manganese. The alloy's composition and manufacturing process contribute to the final product's quality, and the ultimate temper of the alloy is produced through mechanical and thermal treatments, which are heavily influenced by the production method. 

The alloy and temper substantially impact the structural integrity and some physical qualities of a material. You can enhance aluminum's desired properties by alloying it with other metals to generate corrosion resistance, higher strength, or enhanced flexibility, among other benefits. What constitutes an ideal ratio of alloying elements is contextual, based on the final product's intended use.


Which Aluminum Grades are Used in Extrusion?


1050 Aluminum 


This alloy is at least 99% pure aluminum and is used in applications that require high thermal and electrical conductivity. Also, this aluminum grade's excellent corrosion resistance and workability are not influenced by its low strength. Automotive and electrical industries frequently employ this non-heat-treatable alloy for heat transfer applications. The 1050 alloy outperforms other metals in resistance to corrosion and thermal conductivity.

6060 Aluminum


You can easily extrude this grade despite its complicated cross sections and moderate strength that is just below 6005A but greater extrudability than 6063, making it a good compromise between the two. In its T4 condition, aluminum extrusion is at its most popular because of the metal's good workability and suitability.

In addition to having an excellent anodizing response, this alloy is widely utilized in applications like window frames and furnishings because of its versatility. 

6061 Aluminum


This magnesium-silicon alloy is the finest option to substitute low-carbon steel when necessary for welding or brazing. Features like excellent weldability, high strength, corrosion resistance, and heat treatment make it a desirable material.

The 6061 alloys are widely employed in the building industry and are especially popular for usage in the auto and marine industries.

6005A Aluminum


This grade's excellent strength makes it useful for extrusion operations that don't require overly intricate cross sections. The 6005A grade is flexible enough to be used in closed and open extrusion designs to construct staircases, bridges, protective anodizing processes, and scaffolding, among other applications. It is also ideal for load-bearing applications like offshore transportation and construction sectors.

6063 Aluminum


Among the heat-treatable alloys, this one is very common. To get the greatest aesthetic results from anodizing, go with the 6063 alloy, which has a finer grain structure than 6061. It has excellent surface finishes, workability, corrosion resistance, weldability, and cost-efficient. Heat sinks, electrical bus conductors, cylinder tubing, and architectural applications are all common uses.

6082 Aluminum


Although this alloy isn't the best option for cosmetic anodizing, it makes a great choice for structural elements that need to withstand a lot of stress; hence the 6082 alloys are used in truck trailer floorboards and sidewall profiles.

6105 Aluminum


Alloy 6105 is an aluminum alloy with moderately high strength comparable to alloy 6061 despite its increased silicon content. The T1 temper is aged naturally and is suitable for bending tasks.

Because of the higher silicon content, the alloy's characteristics might improve more quickly with age than with a standard 6063 or 6061 alloy. If you need to extrude a complex shape but have trouble with 6061, use 6105 instead because easier to work with.

 7180 Aluminum


The alloy offers great strength but is difficult to shape or extrude. Extreme techniques can make it less prone to corrosion in high-stress areas. The 7180 alloys are commonly utilized in vehicle manufacturing and construction projects that require extra strength, and you can weld this alloy in load-bearing portions. Additionally, it can be anodized for security purposes.
