3. Application Fields of C17500
It is mainly used for fuse clips,fasteners,spring switches,relay parts.
Copper beryllium alloys feature high strength and good thermal and electrical properties. Two main types of copper beryllium alloys are high conductivity alloys and high strength alloys. The high conductivity alloys have 0.2-0.7% of beryllium and high cobalt and nickel contents. The wrought high strength alloys consist of 1.6 to 2.0% of beryllium and nearly 0.3% of cobalt.
