Aluminum 1100

Material Data Sheet

The aluminum 1100 alloy is a pure aluminum alloy with excellent forming characteristics. Aluminum  1100 alloy has excellent machinability especially when the alloy is machined in hard temper. Aluminum 1100 is among the softest aluminum alloy, and it is not to be used for high-strength or high-pressure applications.
