High-end beryllium copper alloys are mainly used in mechanical and electronic industries. Due to its excellent and unique properties as a conductive spring material, it is mainly used in connectors, IC sockets, switches, relays, micro motors and automotive electrical devices. Adding 0.2~2.0% of beryllium to copper, its strength is the highest in copper alloys, and it also has excellent relationship between tensile strength and electrical conductivity. In addition, its formability, fatigue resistance and stress relaxation are also other Copper alloys can’t match. Its main points can be summarized as follows:
1. Sufficient hardness and strength: After many tests, beryllium copper can reach the maximum strength and hardness through the hardening conditions of precipitation.
2. Good thermal conductivity: The thermal conductivity of beryllium copper material is conducive to controlling the temperature of plastic processing molds, making it easier to control the molding cycle, and at the same time ensuring the uniformity of the mold wall temperature;
3. Long service life of the mold: Budgeting the cost of the mold and the continuity of production, the expected service life of the mold is very important for the manufacturer. When the strength and hardness of beryllium copper meet the requirements, beryllium copper will affect the mold temperature. The insensitivity of stress can greatly improve the service life of the mold,
4. Excellent surface quality: Beryllium copper is very suitable for surface finishing, can be directly electroplated, and has very good adhesion properties, and beryllium copper is also easy to polish.
