Copper-nickel alloy, also known as white copper, is a copper-based alloy with nickel as the main additive. It is silvery white and has a metallic luster, hence the name white copper. Copper and nickel can be infinitely soluble in each other. Compared with other copper alloys, white copper has excellent mechanical and physical properties, good ductility, high hardness, beautiful color, corrosion resistance and good deep drawing performance. Widely used in shipbuilding, petrochemical industry, electrical appliances, instruments, medical devices, daily necessities, handicrafts and other fields, and is also an important resistance and thermocouple alloy. The disadvantage of white copper is that the main added element-nickel is a scarce strategic material, and its price is relatively expensive.
Nickel white copper (copper-nickel-zinc alloy), uses: crystal oscillator shell, crystal shell, potentiometer slider, medical machinery, building materials, etc.
