White copper alloys containing elements such as manganese, iron, zinc, and aluminum are called complex white copper (i.e. white copper with three or more elements), including iron white copper, manganese white copper, zinc white copper, and aluminum white copper. In complex white copper, the second main element symbol and the numerical group of components other than copper content represent the content of various elements. BMn3-12 represents a nickel content of approximately 3% and a manganese content of approximately 12%. There are four models of complex white copper:
① Iron white copper: Models include BFe5-1.5 (Fe) -0.5 (Mn), Bfe10-1 (Fe) -1 (Mn), and Bfe30-1 (Fe) -1 (Mn). The addition of iron in iron white copper should not exceed 2% to prevent corrosion and cracking. Its characteristics are high strength and significantly improved resistance to corrosion, especially to flowing seawater corrosion.
② Manganese white copper: Models include BMn3-12, BMn4.0-1.5, and BMn43-0.5. Manganese white copper has a low temperature coefficient of resistance, can be used over a wide temperature range, has good corrosion resistance, and also has good processability.
③ Zinc white copper: Models include BZn18-18, BZn18-26, BZn18-18, BZn15-12 (Zn) -1.8 (Pb), BZn15-24 (Zn) -1.5 (Pb). Zinc white copper has excellent comprehensive mechanical properties, excellent corrosion resistance, good cold and hot processing formability, easy cutting, and can be made into wires, rods, and plates, which are used to manufacture precision parts in the fields of instruments, meters, medical devices, daily necessities, and communications.
④ Aluminum white copper: models include Bal13-3 and Bal16-1.5. It is an alloy formed by adding aluminum based on copper nickel alloy, with a density of 8.54-0.3. The alloy performance is related to the ratio of nickel and aluminum in the alloy. When Ni: Al=10:1, the alloy performance. Commonly used aluminum white copper includes Cu6Ni1.l, Cul3Ni3Al, etc., mainly used for various high-strength and corrosion-resistant parts in industrial sectors such as shipbuilding, power, and chemical engineering.
Ordinary white copper
Copper nickel binary alloy (i.e. binary white copper) is called ordinary white copper. In ordinary white copper, the letter B represents the amount of nickel added, for example, B5 represents a nickel content of about 5%, and the rest is about copper content. The models are B0.6, B19, B25, and B30.
Industrial white copper
Industrial white copper is divided into two categories: structural white copper and precision resistance alloy white copper (electrical white copper).
