Aluminum bronze strength, wear resistance and corrosion resistance for casting high-load gear, bushings, marine propeller Chromium copper is good thermal conductivity properties, high hardness, wear the antiknock, commonly done conductive block. The orthostatic good playing the sheet bend. Beryllium copper is a copper-based alloy of a supersaturated solid solution, the mechanical properties, physical properties, chemical properties, and resist performance Orleans Copper alloy Good combination of non-ferrous alloys, solid solution and aging treatment, with special steel with very high strength limit, 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 the manufacture of various types of mold inserts alternative to steel production of high precision, complex shape of the mold, welding electrode materials die-casting machines, injection molding machines punch, such as wear and corrosion, beryllium copper strip used in micro-motor brush, cell phone batteries, computer connectors, all kinds of switch contacts, springs, clips, gaskets, diaphragm, on the film together, and other products. Is indispensable in the development of national economy, an important industrial material. The the density 8.3g/cm3 Hardness 36-42HRC conductivity of ≥ 18% IACS tensile strength ≥ 1000Mpa thermal conductivity of ≥ 105w/m.k20 ℃
