Beryllium copper 275C is an alloy. Beryllium copper casting alloy parts have high conductivity and high strength. Precision casting, gravity casting, sand casting, centrifugal casting and pressure casting can all be used to produce beryllium copper castings. The high content of beryllium makes the alloy liquid Increased fluidity and has a clean function. Beryllium copper has excellent precision replication performance and can be solid solution and aging heat treated to achieve the required strength and hardness. The Rockwell hardness can reach HRC40 after heat treatment.
