Beryllium-Free Copper Mould Making Alloy Features High Strength, Thermal Conductivity

AMPCO Metal, an integrated producer and distributor of specialty copper alloys, employs proprietary manufacturing processes and complex alloy compositions to give its Ampcoloy® 944 copper-silicon-chromium alloy for mould making unique properties. Distinctive for being free of beryllium, this strong copper alloy offers mould makers an attractive balance of hardness (28 HRc on average) and thermal conductivity (156 W/mK, five to six times greater than P20 tool steel and six to seven times greater than H-13 tool steel), and an electrical conductivity of approximately 35% IACS.
