The correct alloy for your aluminium profile

We produce all standard and custom aluminium extrusion alloys and tempers, shapes and sizes by direct and indirect extrusion. We also have the resources and ability to create custom alloys for customers.

Choosing the right alloy for extruded aluminium

Pure aluminium is relatively soft. To overcome this, it can be alloyed with other metals. We have developed aluminium alloys that are tailored to cover most of the applications in the industry. They are available globally.

The infinite number of extruded aluminium applications

The extrusion process, combined with the proper selection of alloy and quenching, provides an infinite number of extruded aluminium profile applications and product improvements. For instance, Alloy 6060 offers a corrosion-resistant extrusion with an excellent finish. Alloys can be improved by heat treatment after extrusion.

Here are descriptions of some of the aluminium alloys that we use in your extruded product solutions:

3003/3103 alloys

These non-heat treatable alloys feature good corrosion resistance, workability and weldability. The 3003/3103 alloys develop strengthening from cold working only and are typically used in the automotive and HVACR industries. They offer good corrosion resistance and mechanical properties that exceed 1xxx-series alloys. Applications include radiators for cars and air conditioning evaporators.

5083 alloy

This alloy is easier to weld than 6xxx-series alloys and is more predictable in terms of post-weld strength. The 5083 alloy excels in corrosion resistance in a salt-water environment and is therefore the material of choice for marine hull structure applications.

6060 alloy

This alloy is most frequently used in applications that require the highest quality finish, and where strength is not the crucial factor. Applications that use the 6060 alloys include picture frames and exclusive furniture.

6061 alloy

This magnesium and silicon alloy is the best choice when welding or brazing is required. It has structural strength and toughness, good corrosion resistance and good machining characteristics. The 6061 alloys is used extensively as a construction material, most commonly in the manufacture of marine and automotive components.

6082 alloy

This alloy is not suitable for decorative anodizing, but it certainly qualifies as an excellent choice for high-strength building and structural components. Applications for the 6082 alloy include trailer profiles for trucks as well as for floors.

The 7108 alloy has high strength and good fatigue strength, but limited extrudability and formability. It is susceptible to stress corrosion in areas with high stresses. Welding should only be carried out in areas where the loading is lower. Typical applications are structures for building and transport applications where high strength is required. The material is suitable for anodizing for protective purposes.
