The strength, corrosion resistance, hardness, resistance and thermoelectric properties of pure copper and nickel can be improved obviously, and the temperature coefficient of resistivity can be lowered. White copper is superior to other copper alloys in mechanical and physical properties, good ductility, high hardness, elegant luster, corrosion-resistant White Copper Mountain ink cartridge, rich deep drawing properties. It is widely used in shipbuilding, petrochemical industry, electrical appliances, instrumentation, medical equipment, daily necessities, handicrafts and other fields, as well as important resistance and thermocouple alloys. The defect of white copper is an important additive element - nickel is a scarce strategic material with low price. Nickel white copper (called Ocean white copper) is used for: crystal oscillator shell, crystal shell, slider for potentiometer, medical machine, building materials, etc.
