Introduction
Aluminum alloys are good low-temperature alloys with high electrical conductivity. These alloys have strong corrosion resistance characteristics and are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F). When exposed to subzero temperatures the aluminum alloys gain strength, and strength is lost when these alloys are exposed to high temperatures.
The following datasheet provides an overview of the aluminum 5356 alloy.
