Beryllium copper is a copper alloy with beryllium as the main alloying element, also known as beryllium bronze. It is an elastic material in copper alloys, with high strength, elasticity, hardness, fatigue strength, small elastic lag, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, no sparks when impacted, etc. – a series of excellent Physical, chemical and mechanical properties. High-performance beryllium copper mainly focuses on various working conditions of non-ferrous metal low-pressure and gravity casting molds. Through in-depth research on the failure cause, composition and internal relationship of metal liquid corrosion resistance of beryllium bronze mold materials, a high-conductivity (thermal) and high-strength mold has been developed. The beryllium bronze mold material with high performance, not easy to wear, high temperature resistance, good toughness and corrosion resistance of molten metal, solves the problems of low pressure of domestic non-ferrous metals, easy cracking and easy wear of gravity casting molds, and significantly improves the life of the mold , demolding speed and casting strength. Beryllium copper is an alloy with good mechanical, physical and chemical comprehensive properties. After quenching and tempering, it has high strength, elasticity, fatigue resistance and heat resistance, and is not easy to wear. At the same time, beryllium copper also has high electrical conductivity. , thermal conductivity, cold resistance and non-magnetic, no sparks when impacted, easy to weld and braze, good corrosion resistance in the atmosphere, fresh water and sea water. Beryllium bronze alloy is suitable for the manufacture of various molds and wear parts such as cams, gears, worm gears, bearings, etc.
Beryllium is difficult to machine on 5 axis because of its high ductility and high cold workability.Beryllium Copper alloys are often used in place of beryllium copper to improve machinability, especially when performing more intricate custom work. Completed operations include milling, slotting, drilling, tapping,counterboring, Completed operations include milling, slotting, drilling, tapping, counterboring, chamfering, threading, knurling, brazing, grooving, trimming, and nickel plating.
