Advantages and disadvantages of copper plus nickel body can significantly improve strength, corrosion resistance, hardness, resistance and thermal resistance, and reduce the temperature coefficient of resistivity. Therefore, compared with other copper-nickel alloy mechanical properties, physical properties of copper alloys are exceptionally good, brass tape wholesale, ductility, hardness, color and appearance, corrosion-resistant nickel alloy cartridge landscape, full of deep-drawing performance, brass tape, is widely used in shipbuilding, petrochemical, electrical, instrumentation, medical equipment, daily necessities, handicrafts and other areas, brass tape, and also an important resistance and thermocouple alloys. The disadvantage is that the main element of copper-nickel alloy - nickel-strategic materials are scarce, expensive. - Nickel (there called foreign white copper), use: crystal oscillation element housings, crystal case, potentiometers slide film, medical equipment, construction materials. Beryllium copper Beryllium classification process and forging beryllium points. Commonly used forged beryllium and so on. Processing beryllium beryllium-containing 2% or less amount of restraint, domestic beryllium copper participate 0.3% nickel, or cobalt plus 0.3%. Beryllium is used as the primary processing of all types of advanced flexible element, brass reel processing, special functions requiring superior conductivity, corrosion resistance, abrasion resistance, cold resistance, non-magnetic types of elements, many used as the film cartridge, the diaphragm bellows, micro switches. Beryllium copper is mechanical, physical and chemical combined excellent features an alloy by quenching quenching and tempering, with high strength, elasticity, abrasion resistance, fatigue resistance and heat resistance, but also beryllium copper also has high electrical conductivity resistance, thermal resistance, cold resistance and non-magnetic, impact when no spark, easy welding and brazing, excellent corrosion resistance in the atmosphere, freshwater and seawater. Beryllium copper alloy corrosion in seawater velocity: (1.1-1.4) × 10-2mm / years. Erosion Depth: (10.9-13.8) × 10-3mm / years. After erosion, strength, extended no rate change, it can also persist in water for more than 40 years, is a submarine cable repeater structure irreplaceable data. In sulfuric acid medium: sulfuric acid concentration of less than 80% (at room temperature) Erosion depth 0.0012-0.1175mm, concentrations greater than 80% is slightly accelerated erosion.
