1070 Aluminum Bar and Rod

Grade: 1070

Size:

Cold drawn: 2mm-12mm

Extruded: 6mm-400mm

Standard: ASTM, AMS, BS etc.

1070 is commercially pure aluminum with a minimum aluminum content of 99.70 percent. Solid bars and rods offer high electrical and thermal conductivity, good corrosion resistance and excellent ductility. The alloy is not precipitation hardenable; cold working increases strength while reducing formability. Its relatively low strength favors conductive parts and lightly loaded components. Soft material can produce long chips during machining. Electrical service requires conductivity testing and an agreed product specification in addition to chemical compliance.
