Introduction
Aluminium / Aluminum alloys are good low-temperature alloys with
high electrical conductivity and strong corrosion resistance
characteristics. These alloys are sensitive to high temperatures
ranging between 200 and 250°C (392 and 482°F). Aluminium / Aluminum
alloys gain strength when exposed to subzero temperatures and lose
strength when exposed to high temperatures.
The following datasheet provides an overview of Aluminium / Aluminum
5254 alloy.
