Aluminium 6082
Aluminium 6082 is a medium strength alloy with excellent corrosion resistance. In plate form, 6082 is the most commonly used alloy for machining. It also has the highest strength of any alloy in the 6000 series. This strength has meant that 6082 has replaced the older 6061 in many applications.
In the T6 and T651 temper, 6082 machines very well producing tight coils of swarf when chip breakers are used.
6082’s properties means it is typically used in…
· High stress applications
· Trusses
· Bridges
· Cranes
· Transport applications
· Ore skips
· Beer barrels
· Milk churns
