MoldMAX XL? Alloy
Materion Brush Performance Alloys’ MoldMAX XL
Alloy is a high strength copper mold alloy with good thermal
conductivity.The alloy contains no beryllium and is available in
sections as large as 12” thick. The alloy’s hardness is comparable
with AISI P-20tool steel, but its thermal conductivity is two to
three times higher. MoldMAX XL Alloy is used as injection mold
cores andcavities. The alloy provides excellent toughness, wear
resistance and surface finish. MoldMAX XL Alloy typically machines
fasterthan tool steels, and with appropriate machine tools, metal
removal rates several times higher can be obtained
