6063 Aluminum: Get to Know its Properties and Uses

Alloy selection plays an important role in your aluminum extrusion project.

6063 aluminum is the most popular alloy for extrusion and so it is a natural consideration. This alloy is widely used in architectural applications. Because of this, it is often referred to as architectural aluminum.

It is a medium strength alloy, which is used for applications such as railing, window frames, door frames, roofs, balustrading, sign frames, shop fittings, irrigation tubing, building products, electrical, marine, piping, recreation equipment, storage tanks, truck frames & trailers.

This alloy is often extruded in tubing and channels for use in architectural projects.

Comparing 6063 Aluminum to Other Alloys

The 6063 alloy is the most common for extrusion, but you may be considering other options for your particular application. Below are some other common alloys that are often considered as alternatives.

6063 vs 6061

These two alloys are the most popular for extrusion, with 6063 occupying the number one spot and 6061 aluminum in position number two. Both are part of the 6000 series and are alloyed primarily with magnesium and silicon. As such, they possess many of the same qualities. They offer similar corrosion resistance, weldability, and workability. They can both be used in a wide variety of applications.

One key difference is that 6061 is the stronger of the two, and in the T6 temper its strength is approximately equal to structural steel. As such, it is often used for structural applications. One advantage of 6063, on the other hand, is that it’s easier to form into complex shapes with smooth surfaces. It is also very suitable for anodizing.

Summary

6063 aluminum is the most common choice for extrusion with its excellent extrudability, high corrosion resistance, and ability to be formed into complex shapes. It is often used for architectural applications because of its nice appearance an acceptable strength.
