Introduction
Aluminium / Aluminum alloys have high electrical conductivity and strong corrosion resistance. They tend to lose some of their strength at elevated temperatures ranging between 200 and 250°C (392 and 482°F). However, their strength can be increased at subzero temperatures, thus making them a useful low-temperature alloy.
The following datasheet will provide more details about Aluminium / aluminum casting A03560 alloy.
