II. Optimization of Performance through Heat Treatment Process

Heat treatment is a crucial step in improving the overall performance of C17300 beryllium copper. A solution treatment method is typically employed, where the alloy is heated to 1010–1150°C and then rapidly cooled to form a uniform, fine-grained austenitic structure. This process not only enhances the material's strength and hardness but also significantly improves its fatigue resistance and wear resistance. Some products may also undergo aging treatment according to specific requirements to further improve hardness and wear resistance. Proper heat treatment helps eliminate internal stresses generated during the manufacturing process, ensuring dimensional stability and high precision of components during long-term use.
