Background

Aluminium alloy 6262 is a heat treatable alloy with very good corrosion resistance and strength. Additions of bismuth to the alloy mean that Aluminium alloy 6262 has excellent machinability and surface finish.

High-speed steel or carbide tooling can be used to obtain smooth finishes. Heavy cutting requires oil lubricant but light cutting can be done dry.

Aluminium alloy 6262 can be used in place of 2011 when higher corrosion resistance and better anodising response is required.
