Aluminium alloy 6262 is a heat treatable alloy with very good corrosion resistance and strength. Additions of bismuth to the alloy mean that 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. Alloy 6262 can be used in place of 2011 when higher corrosion resistance and better anodising response is required. PLEASE NOTE: Due to European Environmental Protection Directives (2000/53/CE-ELV – For the automotive sector, 2002/95/CE-RoHS – For the electrical and electronics sector), this alloy has been replaced by Alloy 6026 which has a lower Lead content.
Alloy 6262 is commonly used in the manufacture of:
