C17200 beryllium copper is a type of imported beryllium copper.
C17200 beryllium copper, known as the "King of Non-Ferrous Elasticity" in its full series, is used in various micro-motor brushes, switches, relays, connectors, thermostats, and spring strips that require high strength, elasticity, hardness, and wear resistance. As the demand for product reliability and lifespan increases, so will the demand for beryllium copper.
