C17200 copper bar is a high performance beryllium copper alloy that exhibits excellent mechanical properties after special treatment. It has extremely high strength and hardness while maintaining good toughness and fatigue resistance, making it suitable for the manufacture of precision parts and highly wear-resistant components. This material achieves excellent mechanical properties after age-hardening, making it ideal for high-end applications in aerospace, electronics and precision instruments.
In addition, C17200 copper bar not only possesses excellent electrical and thermal conductivity, but also excellent corrosion resistance. Its ability to remain stable over time in wet or chemically aggressive environments reduces maintenance costs and extends service life. These properties make C17200 copper bar widely used in applications requiring high reliability and durability, such as the manufacture of electrical connectors, springs and electrodes.
