Introduction
Aluminium / Aluminum alloys are alloys having high electrical
conductivity and
strong corrosion resistance. These alloys tend to lose some of their
strength at high temperatures ranging between 200 and 250°C (392 and
482°F). However, their strength can be increased at subzero
temperatures, making them a suitable low-temperature alloy.
