애플리케이션
- 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
