Aluminium 6082 T6 & T651

Aluminium T6 6082 Alloy is a medium strength aluminium alloy that provides amazing 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 resistant after forming 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, and 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. 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. -- APPLICATIONS -- 6082 is typically used in: ~ Highly stressed applications ~ Trusses ~ Bridges ~ Cranes ~ Transport applications ~ Ore skips ~ Beer barrels ~ Milk churns -- TEMPER TYPES -- The most common tempers for 6082 aluminium are: T6 – Solution heat treated and artificially aged O – Soft T4 – Solution heat treated and naturally 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 sheet can also be supplied as 6082-T651. -- WELDABILITY -- 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. Gas: Good | Arc: Good | Resistance: Good -- FABRICATION -- Workability - Cold: Good Machinability: Good
