Applications
- 2011 is typically used in applications that require parts manufactured by repetition machining. These applications may include:
- Appliance parts & trim
- Automotive trim
- Fasteners and fittings
- Ordnance
Caractéristiques
- Machining at high speeds produces fine chips that are easily removed. The excellent machining characteristics allow the production of complex and detailed parts. In some circumstances 2011 can replace free machining brass without the need for alterations to tooling.
- It has poor corrosion resistance, which means parts made from 2011 tend to be anodised to provide additional surface protection.
- Alloy 2011 has extremely poor weldability and thus welding is not recommended. However, as it is used for machined parts there is rarely a need to weld this alloy.
