Copper Nickel Alloy

Copper-nickel alloy, copper Cu and nickel Ni, silvery white, metallic luster, so the name white copper.Copper and nickel can be infinitely solid solution between each other, thus forming a continuous solid solution, that is, regardless of the proportion of each other, and constant for the alpha - single-phase alloy.

When the nickel is fused into the red copper D200, the content of more than 16%, the resulting alloy color becomes relatively nearly white, such as silver, the higher the nickel content, the more white color, but, after all, and copper fusion, as long as the proportion of nickel content does not exceed 70%, the naked eye will see the yellow color of copper. What's more, usually the nickel content in white copper is generally 25%. White copper is the elegant name of copper-nickel alloy, density between copper and nickel 8.9-8.88.


Copper Nickel Alloy advantages

Copper-nickel (also known as cupronickel) alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability. They have provided reliable service for decades while offering effective solutions to today's technological challenges.

Copper nickel is more corrosion-resistant than other types of metals.
Copper nickel can withstand higher temperatures than other types of metals.
Copper nickel is non-magnetic.
Copper nickel is less likely to cause an allergic reaction in people who are sensitive to metals.
Copper nickel is less expensive than some other types of metals

Copper Nickel Alloy Properties

Pure copper with nickel can significantly improve the strength, corrosion resistance, hardness, resistance and thermoelectricity, and reduce the resistivity temperature coefficient. Therefore, the mechanical properties and physical properties of white copper are exceptionally good compared with other copper alloys, with good ductility, high hardness, beautiful color, corrosion resistance rich deep punching properties, and is widely used in shipbuilding, petrochemical, electrical, instrumentation, medical machinery, 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, the price is relatively expensive.
