Boehler Uddeholm alloy BeCu172 is a high-strength beryllium copper mold with high thermal conductivity. BeCu Alloy 172 can be supplied in the high-hard (HH) condition at approximately 40 HRC and in the low-hard (LH) condition at approximately 30 HRC. This alloy is used for applications such as pinch-offs and neck rings for blow molds, cores, and inserts in injection molds and injection nozzles and manifolds for hot runner systems. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: CU-781. Producer or source: Böhler-Uddeholm Corporation.
