Alloy Description Composition Applications
6005A 6005A is the weakest of the three structural alloys (6005A, 6061 and 6082).

As with all structural alloys it is difficult to produce thin walled or complicated extrusions in 6005A however, of the structural alloys, it has the best extrusion characteristics and mill surface finish.

6005A is a heat treatable alloy with excellent corrosion resistance. It also has good weldability.

6060 6060 alloy is one of the most common alloys of the 6000 series. It is a heat treatable alloy with very good corrosion resistance and weldability.

It is commonly used in window and door frames in residential and commercial applications.

It is an ideal alloy for very complex cross sections and has a very good anodising response.

6061 6061 is a heat treatable alloy with mechanical properties slightly lower than 6082. It has good corrosion resistance but like 6082 its extruded surface finish is not as good as 6060. Mg : 0.80 -1.20

6082 6082 has excellent corrosion resistance and the highest strength of the 6000 series structural alloys. As with all structural alloys the extruded surface finish is not as good as alloys such as 6060 or 6063.

The higher strength of 6082 has seen it replace 6061 in many applications.

6082 has good weldability and when DNV(Det Norske Veritas) certifi ed it is commonly used in marine applications.
