Zamak 2

Zamak 2 offers the highest tensile strength, hardness and creep performance compared to the other zinc die casting alloys in the ZAMAK family.  Its higher copper content (3%) contributes to some of the improved mechanical properties but also affects the casting's dimensional changes after ageing (0.0014 in/in after 20 years).  This alloy is also easily cast, coated and machined as is typical with each of the ZAMAK alloys.
