  • The Zinc alloy ZA8 is a common zinc die casting alloy.
  • The alloy meets all the mechanical property requirements -- strength, ductility, and modulus.
  • But the zinc has 2 major shortfalls against the design requirements --
    • The thermal conductivity is about 4% short of the requirement.
    • The zinc has a major weight penalty, weighing 150% more than the aluminum alloy.
  • The zinc alloy is not the best choice.
