Aluminium 6082 T6 Bar & Extrusions
Structural aluminium alloy with the highest strength in the 6000 series.
Aluminium alloy 6082 is a medium strength alloy with excellent corrosion resistance. It has the highest strength of the 6000 series alloys and is known as a structural alloy.
In plate form, 6082 is the alloy most commonly used for machining. As a relatively new alloy, the higher strength of 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.
It is difficult to produce thin walled, complicated extrusion shapes in alloy 6082. The extruded surface finish is not as smooth as other similar strength alloys in the 6000 series.In the T6 and T651 temper, alloy 6082 machines well and produces tight coils of swarf when chip breakers are used.
