Beryllium copper alloy is mainly used in the mechanical and electronic industries. Due to its excellent and unique performance as a conductive spring material, it is mainly used in connectors, IC sockets, switches, relays, micro motors and automotive electrical components. Adding 0.2*2.0% bismuth to copper, its strength is the highest in copper alloy, and it also has excellent tensile strength and electrical conductivity, and its formability, fatigue resistance and stress relaxation are also other copper. The alloy is out of reach. The main advantages boil down as follows:
1. Sufficient hardness and strength: After many times of testing, the hardening conditions precipitated by precipitation cause the beryllium copper to achieve maximum strength and hardness.
2. Good thermal conductivity: The thermal conductivity of beryllium copper material is beneficial to control the temperature of the plastic processing mold, and it is easier to control the molding cycle, and at the same time ensure the uniformity of the mold wall temperature;
3. Long service life of the mold: the cost of the budget mold and the continuity of the production, the expected service life of the mold is very important for the manufacturer. In the case where the strength and hardness of the beryllium copper meet the requirements, the copper is on the mold. The insensitivity of stress can greatly contribute to the service life of the mold.
4. Excellent surface quality: Beryllium copper is very suitable for surface finishing. It can be directly plated, and the adhesion performance is very good. The polishing of beryllium copper is also very easy.
