Introduction
Magnesium is a strong, silvery-white, light weight metal that tarnishes slightly when exposed to air. It is easy to ignite when powdered or made into thin strips. Magnesium WE43A-T6 alloy has good corrosion resistance and high strength at room and elevated temperatures up to 290°C (550°F).
The following datasheet gives an overview of magnesium WE43A-T6 alloy.
