Application

The full range of beryllium copper is known as the "king of non-ferrous metal elasticity" for all kinds of micro-motor brushes, switches, relays, connectors, thermostat springs that require high strength, high elasticity, high hardness and high wear resistance. Pieces, all kinds of spring pieces, as the requirements for product reliability and service life are getting higher and higher, the demand for beryllium copper will also become larger and larger.

Injection molds and high pressure blow molds, mold inserts, rapid cooling, aluminum alloy mold inserts, increase strength, wear resistance and shorten injection cycle, hot runner nozzles, electrodes and punch materials, free from magnetic molds, non-magnetic tools , high thermal conductivity bearing, can produce mirror surface with high surface precision.
Commonly used enamel bronze grades are as follows:
C17200 / C17300 / C17000 is a high strength deformed alloy;
C17500 / C17510 is a highly conductive deformed alloy;
BeA-275C/BeA-20C is a high strength cast alloy;
BeA-10C/BeA-50C is a highly conductive casting alloy
