Applications
- Screw machine products
- Camera parts
- Nuts
- Couplings
- Marine fittings
- Decorative hardware and appliance fittings
- Hinge pins
- Oil line fittings
- Valves and valve parts
Characteristics
- Very good corrosion resistance
- Very good strength
- Excellent machinability and surface finish due to additions of bismuth
- 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
Additional Information
Weldability
Alloy 6262 is readily weldable by all commercial methods and can also be brazed.
