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
