About Kirksite

Kirksite is an alloy comprised primarily of zinc.  It also contains
aluminum (3.5-4.5%), copper (2.5-3.5%).  Kirksite is primarily used for
sheet metal forming tooling and plastic injection molds for prototype
and short run production applications.



There are several advantages to kirksite tooling
  • Low melting point allows fast turnaround
  • Good machinability, changes can be made easily
  • Accurate "precision" casting reduces need for machining, especially on draw dies
  • Can be electroplated
  • Excellent tensile strength (35,000 psi)
  • Excellent fluidity when molten, large jobs can be pumped quickly
