Aluminium 6082 Alloy

6082 aluminium has the highest strength of all the 6000 series alloys.

The higher strength of Aluminium alloy 6082 has seen it supersede 6061 in many applications. The extra-large amount of manganese dictates the grain structure which as a result gives you a stronger alloy.

In the T6 and T651 temper, Aluminium alloy 6082 machines well and gives off tight coils of swarf when chip breakers are introduced.

Often referred to as a 'structural alloy', 6082 or HE30 as it is also known can be used in projects that have high stress involved such as cranes and bridges. The alloy offers excellent corrosion resistance and has replaced 6061 in many areas. The extruded version is not as smooth as other 6000 series alloys.

Key Features:

6082 offers good excellent with excellent corrosion resistance. Available in bar, plate, sheet and tube, the alloy is used in many structural applications.

Typical Applications:

  • Roof trusses
  • Precision Engineering Projects
  • Milk churns
  • Bridges
  • Cranes
  • Ore skips

Fabrication

Workability - Cold: Good

Machinability: Good

 

Weldability

6082 has excellent weldability but strength suffers in the weld zone. When welded to itself, alloy 4043 wire is ideal. If welding 6082 to 7005, then the wire used should be alloy 5356.

Weldability – Gas: Good

Weldability – Arc: Good

Weldability – Resistance: Good

Brazability: Good

Solderability: Good
