Product Description

Product Description

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.

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.

Applications

Among copper alloys, white copper is widely used in shipbuilding, petroleum, chemical industry, construction, electric power, precision instrumentation, medical equipment, musical instrument making and other sectors as corrosion-resistant structural parts because of its excellent corrosion resistance and ease of shaping, processing and welding. Some white copper also has special electrical properties, can make resistance components, thermocouple materials and compensation wire. Non-industrial white copper is mainly used to make decorative crafts.
