Introduction
Aluminum alloys contain have strong corrosion resistance characteristics and
high electrical conductivity. These alloys obtain high strength when exposed to
subzero temperatures and experience a decrease in strength when exposed toat
high temperatures ranging between 200 and 250°C (392 and 482°F). Hence,
Aaluminum alloys are known as good low-temperature alloys and are sensitive to
high temperatures ranging between 200 and 250°C (392 and 482°F).
