1100 aluminium alloy is an aluminium-based alloy in the "commercially pure" wrought family (1000 or 1xxx series). With a minimum of 99.0% aluminum, it is the most heavily alloyed of the 1000 series. It is also the mechanically strongest alloy in the series, and is the only 1000-series alloy commonly used in rivets. At the same time, it keeps the benefits of being relatively lightly alloyed (compared to other series), such as high electrical conductivity, corrosion resistance, and workability. It can be strengthened by cold working, but not by heat treatment.

Alternate designations include Al99.0Cu and A91100. 1100 and its various tempers are covered by the ISO standard 6361 and the ASTM standards B209, B210, B211, B221, B483, B491, and B547.

Technical Data Sheet

 

 

Aluminum 1100 is a commercially pure aluminum. 1100 has excellent welding characteristics; it is also soft and ductile so is ideal for applications that require intricate forming as it work hardens slower than other alloys. 1100 is however non-heat treatable. As 1100 has excellent resistance to corrosion it is widely used in the chemical and food processing industries also for giftware and applications where eye appeal is important.
