Grade 6082 Aluminium alloy is a medium strength alloy that possesses excellent corrosion resistance.

Grade 6082 is commonly known as a structural alloy and provides the highest strength of all the alloys in the 6000 series.  This increase in strength is due the addition of a large quantity of manganese that controls the grain structure and creates a stronger alloy.


6082 alloy can be solution heat treated and artificially ages to create 6082T6.

Grade 6082 alloy provides increased strength and hardness when compared to 6063. This means that 6082 can endure higher levels of stress. The alloy machines well and can produce tight coils of swarf if you use chip breakers.

Chemical Composition of 6082


  Cu Mn Si Fe Mg Cr Zn Ti Ai
Min   0.4 0.7   0.6        
Max 0.1 1.0 1.3 0.5 1.2 0.25 0.2 0.1 Balance



Grade 6082 Aluminium alloy provides good weld ability, however the strength located at the weld zones is lowered.

If you are welding 6082 alloy to its self then it is recommended that alloy 4043 wire is used. If you want to weld 6082 to 7005 alloys, then the recommended wire should be 5356 alloy.
