  • Three to Six times higher thermal conductivity than P20 steel
  • Three to Five times faster milling on existing equipment
  • Up to Four times faster polishing
  • Accepts surface treatments for increased hardness
  • Dimensionally stable
  • Supplied stress relieved, requiring no further thermal treatment
  • Repair welding by TIG/MIG is possible


  • Plastic injection molds
  • Blow molds
  • Vacuum forming
  • RIM molds
  • Foam molds
  • Jigs and Fixtures

Molds designed with Alumold 500 should see maximum operating temperature of 230°F
for the mold, not the plastic, and a parting line stress of 5000 psi nominal and 7200 psi maximum.
