C 17200 beryllium copper, the whole series of beryllium copper is called "the king of elasticity of non-ferrous metals", which is used for various micromotor brushes, switches, relays and connectors that require high strength, high elasticity, high hardness and high wear resistance. With the improvement of product reliability and service life, the demand for beryllium copper will also increase.

Beryllium bronze combines excellent mechanical properties, physical properties and chemical properties. After heat treatment (solution treatment and aging treatment), it has the high strength limit, elastic limit, yield limit and fatigue limit equivalent to special steel. At the same time, it has the characteristics of high electrical conductivity, thermal conductivity, high hardness, corrosion resistance, wear resistance, good casting performance, no magnetism, no impact spark and so on, and is widely used in mold manufacturing, machinery, electronics and other industries.

No sand holes and pores, balanced hardness, compact structure, high strength, good thermal conductivity, good electrical conductivity, corrosion resistance, excellent wear resistance, good machinability, stable performance under high pressure, no magnetism, excellent polishing performance and good adhesion resistance.
