Aluminium T6 6082 Alloy

Aluminium T6 6082 Alloy

6082 t6 aluminium plateAluminium T-6 6082 Alloy: is a medium strength aluminium alloy that provides amzing corrosion resistance and is commonly used for application jobs that require light to medium strength. Aluminium 6082 is the strongest of the 6000 series alloys.
Aluminium t-6 6082 aluminium alloys bring together great rust resistance and strength after many different types of heat treatments. It also remains strong and rust resistance after form and welding. Aluminium 6082 is the most common heat treated alloy plate from stock. In plate form, 6082 is the alloy most commonly used for machining.

It can be found in a number of construction and building projects such as Trusses, bridges, Cranes, high quality ore skips. It is also found in highly stressed applications like beer barrels, milk churns and has a huge range of transport applications.

6082 – T6~T651 Plate


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, 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.

6082 is typically used in:
~ Highly stressed applications
~ Trusses
~ Bridges
~ Cranes
~ Transport applications
~ Ore skips
~ Beer barrels
~ Milk churns

Alloy Designations

Aluminium alloy 6082 also corresponds to the following standard designations and specifications but may not be a direct equivalent:



DIN 3.2315

EN AW-6082

ISO: Al Si1MgMn




Temper Types

The most common tempers for 6082 aluminium are:

  • T6 – Solution heat treated and artificially aged
  • O – Soft
  • T4 – Solution heat treated and naturaly aged to a substantially stable condition
  • T651 – Solution heat treated, stress relieved by stretching then artificially aged



Supplied Forms

Alloy 6082 is typically supplied as Channel, Angle, Tee, Square bar, Square box section, Rectangular box section, Flat bar, Tube and Sheet

Plate and shate can also be supplied as 6082-T651

  • Extrusions
  • Bar
  • Plate
  • Sheet
  • Tube




6082 has very good weldability but strength is lowered in the weld zone. When welded to itself, alloy 4043 wire is recommended. If welding 6082 to 7005, then the wire used should be alloy 5356.
