The ZA 8, or zinc aluminum alloy contains significantly more aluminum than the Zamak group of alloys. This alloy has the highest creep strength of any zinc alloy and the highest strength of any hot-chamber die cast zinc alloy.

ZA-8, or zinc aluminum alloy, contains significantly more aluminum than the Zamak group of alloys. ZA-8 contains approximately 8.4% aluminum and is the only ZA alloy that can be hot-chamber die cast, an important consideration when selecting a material for a component. 

• ZA-8 has excellent finishing and plating characteristics and was originally developed as a permanent mold alloy
• It is ideal for decorative applications
• Although it does not have as good casting characteristics as the other zinc alloys, it offers significantly improved strength, hardness, and creep properties
