Becu Beryllium Copper Wire Alloy25 JIS C1720 Spring Wire Strip XHM Hard Treatment
Beryllium copper is a supersaturated solid solution copper-based alloy, a copper alloy with bismuth as the main alloying element, also known as beryllium bronze.
Features:
Beryllium copper is an alloy with good mechanical, physical and chemical properties. After quenching, it has high strength, elasticity, wear resistance, fatigue resistance and heat resistance, with feature of high conductivity,thermal conductivity, cold resistance and non-magnetic, no sparks when hitting, easy to weld and excellent corrosion resistance in the atmosphere, fresh water and seawater.
Usage:
Casting beryllium bronze: (Cu-2Be-0.5Co-0.3Si, Cu-2.6Be-0.5Co-0.3Si, Cu-0.5Be-2.5Co, etc.) For explosion-proof tools, various molds (inner inserts for plastic injection molding dies, integral cavities for blow molds, automotive molds), bearings, bushings, bushings, gears and various electrodes
Processing beryllium bronze: (Cu-2Be-0.3Ni, Cu-1.9Be-0.3Ni-0.2Ti) is mainly used as a variety of advanced elastic components, especially requiring good conductivity, corrosion resistance, wear resistance, cold resistance, various no magnetic components, used as a large number of bellows, diaphragms, bellows, micro switches, etc.
