6082 aluminium alloy is a medium strength alloy in the aluminium-magnesium-silicon family with excellent corrosion resistance. It has the highest strength of the 6000 series alloys. Alloy 6082 is known as a structural alloy. In plate form, 6082 aluminium alloy is the alloy most commonly used for machining.
As a relatively new alloy, the higher strength of Aluminium alloy 6082 has replaced 6061 in many applications. The addition of a large amount of manganese controls the grain structure which in turn results in a stronger alloy. Aluminium alloy 6082 is tipically used in high stress applications, transportation, cranes, bridges, etc.
