Introduction
Aluminium / Aluminum alloys have strong corrosion resistance and high electrical conductivity. These alloys tend to lose some of their strength at high temperatures ranging between 200 and 250°C (392 and 482°F). However, they can gain strength at subzero temperatures, making them a useful low-temperature alloy.
The following datasheet will provide more details about Aluminium / aluminum casting A03190 alloy.
