ZK21A
UNS M16210
Description
Magnesium alloy ZK21A is a non-hard enable extruded magnesium-base alloy having moderate strength and good weldability. ZK21A-F alloys have been developed in an effort to obtain mechanical properties that are halfway between magnesium AZ31B and ZK60A alloys; good weldability in contrast to magnesium ZK60A alloy and freedom from stress relief requirements in contrast to magnesium AZ31B alloy.
