AL6082 T651

What is Aluminium Alloy 6082?

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. Both 6082-T6 aluminum and 6082-T651 aluminum are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing.

Applications

6082 is typically used in:

Highly stressed applications

Trusses

Bridges

Cranes

Transport applications

Ore skips

Beer barrels

Milk churns

Main Attributes:

Medium strength

Excellent corrosion resistance

Extruded surface finish not as smooth as others in the 6000 series

Lightweight

Good weldability but strength lowered in the weld zone

Also good for brazing & soldering

Suitable for outdoor applications and will not rust

Does not perform as well when exposed to saltwater as 5000 series grades

Finishing & Treatments:

6082 is a suitable aluminium grade for successful anodising which offers good protection. Options include:

Natural sulphuric anodise

Colour sulphuric anodise 

Natural hard anodise 

Colour hard anodise

Chromate and non-chromate conversions (Alochrom 1000/1200 - Not RoHS compliant) (Iridite NCP/Surtec 650 new versions of Alochrom)
