Material Notes:

Description: Brush Wellman’s MoldMAX XL® 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-20 tool steel, but its thermal conductivity is two to three times higher. MoldMAX XL® is used as injection mold cores and cavities. The alloy provides excellent toughness, wear resistance and surface finish. MoldMAX XL® typically machines faster than tool steels, and with appropriate machine tools, metal removal rates several times higher can be obtained.Information provided by Schmolz + Bickenbach
