Magnesium Alloy ZK60

Magnesium Alloy ZK60A is the typical legacy magnesium ligature. The current and historical uses are in the rotor and military aircraft, while the largest volume application is made of magnesium wheels forged for motorsport. This high strength alloy has good corrosion resistance but requires a coating for all applications.
