3.2315 | EN AW 6082 | AlMgSi1

EN AW 6082 (3.2315) is a high-strength aluminum–magnesium–silicon alloy for structural and mechanically demanding applications.
The material is particularly suitable for mechanical engineering, vehicle construction, fixtures and load-bearing structural components.
Compared with EN AW 6061, 3.2315 is often preferred when higher strength is required while maintaining similar machinability.
The alloy provides very good corrosion resistance, including in marine environments, and is also food-contact suitable and RoHS-compliant.

Eigenschaften von 3.2315 im Detail

Detail

Weldability

EN AW 6082 shows good weldability. Most welding processes are suitable for this alloy, especially TIG and MIG welding. The material is very resistant to cracking, thanks to the magnesium and silicon additions, similar to EN AW 6060. Post-weld heat treatment is generally not required but can be used to optimize mechanical properties.

Detail

Machinability

EN AW 6082 has moderate overall machinability, with somewhat better results in the heat-treated condition than in the fully annealed state. Use of carbide or HSS tooling is recommended to extend tool life. Machining typically produces short, well-controlled chips, which simplifies chip evacuation. Tight tolerances are achievable.

Detail

Forgeability

EN AW 6082 forges very well in both closed-die and open-die processes. When heated to the correct forging temperature the material forms easily and shows minimal tendency to crack. Post-forging heat treatment is usually not necessary.

Detail

Magnetizability

Aluminum is non-magnetic; the silicon and magnesium alloying does not impart magnetic properties.

Detail

Corrosion resistance

This aluminum alloy provides very good corrosion resistance. It offers strong protection in both atmospheric and saline environments, making it attractive for shipbuilding and plant construction. The alloy is also resistant to stress corrosion and crevice corrosion. Its very good suitability for anodizing allows further enhancement of the protective layer.
