Aluminium, Commercial Alloy6082 T4 Bar & Extrusion

Structural aluminium alloy with the highest strength in the 6000 series.

Known as a “structural” alloy, aluminium alloy 6082 has the highest strength of the 6000 series. The addition of a large amount of manganese controls the grain structure which in turn results in a stronger alloy. 6082 is typically used in highly stressed applications.

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.

Alloy 6082 is typically supplied as channel, angle, tee, square bar, square box section, rectangular box section, flat bar, tube, sheet, shate & plate.
