Beryllium copper BC40 grades H12 content ≥ 98.5 (%) origin Japan 

 Beryllium copper features: - beryllium copper is a supersaturated solid solution copper alloy, mechanical properties, physical properties, chemical properties and good corrosion resistance combined with non-ferrous alloys after solid solution and aging treatment, with special steel is quite high ultimate strength, elastic limit, yield strength and fatigue limit. But also have high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance, widely used in manufacturing various types of mold inserts to replace the steel production of high precision, complex shape of the mold, welding electrode materials, die-casting machine, injection molding machine punch, wear and corrosion work, beryllium copper strip used in micro-motor brush, cell phone batteries, computer connectors, all types of switch contacts, springs, clamps, gaskets, diaphragm , on a film together, and other products. Is an important and indispensable in the national economic construction, industrial materials. Density 8.3g/cm3 hardness 36-42HRC conductivity ≥ 18% of IACS tensile strength ≥ 1000Mpa thermal conductivity ≥ 105w/m.k20 ℃
