Introduction
Aluminium / Aluminum alloys are good low-temperature alloys as they
gain strength when exposed to subzero temperatures. They have strong
corrosion resistance characteristics and high electrical conductivity.
These alloys lose their strength when exposed to high temperatures..
Aluminium / Aluminum alloys are sensitive to high temperatures ranging
between 200 and 250°C (392 and 482°F).
The following datasheet provides an overview of Aluminium / Aluminum
5083 alloy.
