Abstract

MoldMAX XL is a high-strength copper mold alloy with good conductivity. The alloy contains no beryllium and is available in sections as large as 305 mm (12 in.) thick. The alloy’s hardness is comparable to AISI P-20 tool steel, but its thermal conductivity is two to three times higher. This alloy is used as injection mold cores and cavities. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion andwear resistance, and surface qualities as well as forming, machining, and joining. Filing Code: Cu-826. Producer or source: Materion Brush Performance Alloys.
