Commercial Alloy

6005A - T6 Extrusion


Aluminium alloy 6005A is a medium strength, heat treatable alloy with excellent corrosion resistance.

Alloy 6005 has properties between those of alloys 6061 and 6082 and can sometimes be used interchangeably with these alloys, but 6005 has better extrusion characteristics and a better mill surface finish. It is difficult to produce thin-wall or complicated extrusions in 6005, but it is still more extrudable than 6082.

6005A tube has very good bending properties.

Applications
6005 and 6005A typically find application in intricate extrusions like:

~ Tubing for furniture
~ Railway and bus profile structures
~ Pylons, platforms and pipelines
~ Portable ladders
~ Sections where greater strength is needed than given by 6060 and 6063
