Introduction
Aluminum alloys are good low-temperature alloys as they gain
strength when exposed to subzero temperatures. They have high
electrical conductivity and strong corrosion resistance
characteristics. These alloys lose their strength when exposed to high
temperatures. Aluminum alloys are sensitive to high temperatures
ranging between 200 and 250°C (392 and 482°F).
