Copper nickel alloy for copper nickel alloy pipes and fittings: it is a copper base alloy with nickel as the main additive element. Silver white, metallic luster, it is also known as white copper.
Because of the solid solution between copper and nickel, when the nickel content is more than 16%, the color of the alloy will become as white as silver. The higher the nickel content, the whiter the color. The content of nickel in copper nickel alloy is generally 25%.
Cu Ni alloy has the characteristics of corrosion resistance, high hardness, low resistance and thermoelectricity, and can also reduce the temperature coefficient of resistivity. Therefore, compared with other copper alloys, copper nickel alloy has excellent mechanical and physical properties, good ductility, high hardness, beautiful color and deep drawing performance. It is widely used in shipbuilding, petrochemical, electrical appliances, instruments, daily necessities, handicrafts and other fields, and is also an important resistance and thermocouple alloy. The disadvantage of white copper is that nickel, the main additive element, is a scarce strategic material.
