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.

The following datasheet will provide more details about Aluminium / aluminum casting A04130 alloy.
