ZAMAK 8
​​​​​​​
A good gravity casting alloy, Zamak 8 is rapidly growing for pressure die casting. ZA-8 can be hot chamber die cast, with improved strength, hardness and creep properties over ZAMAK’s, with the exception of a zamak 2 alloy which is very similar in performance

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

It is ideal for decorative applications
Zamak 8 has excellent finishing and plating characteristics and was originally developed as a permanent mold alloy
In terms of mechanical performance, ZA-8 has the highest creep strength of any zinc alloy and the highest strength of any hot-chamber die cast zinc alloy
