Brief Introduction Of 6082 Aluminium/Aluminum Alloy:
Aluminium alloy 6082 is a medium strength alloy 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, Aluminium alloy 6082 is the alloy most commonly used for machining.
As a relatively new alloy, the higher strength of Aluminium alloy 6082 has seen it replace 6061 in many applications. The addition of a large amount of manganese controls the grain structure which in turn results in a stronger alloy.
In the T6 and T651 temper, Aluminium alloy 6082 machines well and produces tight coils of swarf when chip breakers are used.
Aluminium alloy 6082 has very good weldability but strength is lowered in the weld zone. When welded to itself, alloy 4043 wire is recommended. If welding Aluminium alloy 6082 to 7005, then the wire used should be alloy 5356.
The most common tempers for Aluminium alloy 6082 are:
O- annealed wrought alloy
T4- Solution heat treated and naturally aged
T6- Solution heat treated and artificially aged
T651- Solution heat treated, stress relieved by stretching and then artificially aged
