Introduction
Aluminum alloys contain strong corrosion resistance. These alloys are good low-temperature alloys. Aluminium / Aluminum alloys are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F). The strength of these alloys increases when exposed to subzero temperatures and the strength decreases when exposed to high temperatures.
