Copper-nickel alloy features: pure copper plus nickel can significantly improve the strength, corrosion resistance, hardness, resistance and thermoelectricity, and reduce the resistivity temperature coefficient. Therefore, the white copper than other copper alloys, mechanical properties, physical properties are exceptionally good, good ductility, high hardness, beautiful color, corrosion resistance is rich in deep-drawn performance.
Use: Widely used in shipbuilding, petroleum, chemical industry, construction, electric power, precision instruments, medical equipment, musical instruments and other departments for corrosion-resistant structural parts. Some white copper has special electrical properties, can make resistance components, thermocouple materials and compensation wire. Non-industrial copper is mainly used to make decorative crafts.
Expanded Information:
Copper-nickel alloys are classified as:
1, complex white copper
Addition of manganese, iron, zinc, aluminum, and other elements of the white copper alloy is called complex white copper ( That is, more than three elements of white copper), including iron copper, manganese copper, zinc copper and aluminum copper. In the complex copper alloy, the second major element symbols and copper content other than the composition of the digital group represents the content of various elements.
2, ordinary copper alloy
Copper-nickel binary alloy (i.e., binary copper alloy) is called ordinary copper alloy. In the ordinary white copper, the letter B indicates the content of nickel.
3, structural copper
Structural copper is characterized by good mechanical properties and corrosion resistance, beautiful color. Structural white copper, the most commonly used is B30, B10 and zinc white copper. In addition, there are aluminum white copper, iron white copper and niobium white copper.
4, precision resistance alloys with white copper (electrical white copper)
Precision resistance alloys with white copper (electrical white copper) has good thermoelectric properties. bMn3-12 manganese copper, bMn40-1.5 copper, bMn43-0.5 copper, as well as manganese instead of nickel, the new copper (nickel-free nickel-free manganese white copper, containing manganese 10.8 ~ 12.5%, aluminum 2.5 ~ 4.5%, Iron 1.0~1.6%) are manganese white copper with different manganese content.
