As part of the casting magnesium alloy, AZ91D is characterized by high specific strength, and corrosion resistance sharply higher than pure magnesium. A represents aluminum(Al), Z representive of zinc, 9 means aluminum content is 9%, 1 on behalf of the zinc content is 1%, the final D as identification code.
