MoldMAX HH is a high-strength copper-beryllium alloy from Materion Brush Performance Alloys for plastic molding applications.
This alloy has a hardness and strength comparable to standard tool steels, but its thermal conductivity is four to six times higher.
MoldMAX HH is used for injection mold cores and inserts as well as blow molds. Its high hardness provides durability in applications where other high conductivity copper alloys fail.
