2011
UNS A92011
Description
Aluminum alloy 2011 is an age hardenable alloy noted for its good machinability (especially free cutting qualities), and high mechanical strength. And the addition of copper and lead in alloy 2011 improves the strength and machinability, respectively. The free cutting properties of the 2011 alloy allow the use of either carbide or high-speed tool steel tooling and make it an ideal choice for use on intricate designs or for complex and detailed parts. The drawback of the improved strength and machinability is that the 2011 has a poor corrosion resistance. Therefore, anodising will be required for additional surface protection. In addition, aluminum alloy 2011 also has excellent surface finish capabilities, but with very poor weldability.
