Aluminium Alloy - Commercial Alloy - 6262 - T6 Extrusions

6262 - T6 Extrusions

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.

Applications
6262 is commonly used in the manufacture of:
Screw machine products
Camera parts
Nuts
Couplings
Marine fittings
Decorative hardware and appliance fittings
Hinge pins
Oil line fittings
Valves and valve parts

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This alloy has been replaced by Alloy 6026 which has a lower Lead content.
