Characteristics And Uses Of Copper Nickel Alloys
Jun 14, 2018

Copper nickel alloy: copper based alloy with nickel as the main addition element. It is silver white and has metallic luster, so it is also called white copper.

Because copper and nickel can be dissolved in infinite solution, when the nickel content exceeds 16%, the alloy color becomes white as silver, the higher the nickel content, the more white the color. The nickel content in the copper nickel alloy is generally 25%.

Cupric nickel alloy has the characteristics of high strength, corrosion resistance, high hardness, low resistance and thermoelectricity. It can also reduce the resistivity temperature coefficient. Therefore, copper and nickel alloys have good mechanical properties and physical properties compared with other copper alloys, with good ductility, high hardness, beautiful color, corrosion resistance and deep drawing properties, and are widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical instruments, daily necessities and crafts, and it is also an important resistance and heat. Electric couple alloy. The disadvantage of white copper is that it mainly adds elements - nickel is a scarce strategic material.
