MoldMAX LH

Materion’s MoldMAX LH (Low Hard) alloy is a premium copper mold alloy that provides hardness and strength comparable with standard AISI P-20 tool steel and a thermal conductivity five-times higher. MoldMAX LH alloy is used for injection mold cores and cavities where moderate hardness and high toughness and conductivity are required.

  • High thermal conductivity
  • Good corrosion resistance
  • Good resistance to galling
  • Good machinability
  • Moderate strength and hardness
  • Excellent weldability
