Classification of White Copper:

I. Complex White Copper

White copper alloys with added elements such as manganese, iron, zinc, and aluminum are referred to as 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 symbol of the second main element and the composition numbers beyond the copper content indicate the content of various elements. For example, BMn3-12 indicates a nickel content of about 3% and a manganese content of about 12%. Complex white copper has four types:

① Iron White Copper: Models include BFe5-1.5 (Fe)-0.5 (Mn), BFe10-1 (Fe)-1 (Mn), BFe30-1 (Fe)-1 (Mn). The iron content in iron white copper does not exceed 2% to prevent corrosion cracking. Its characteristics include high strength and significantly improved corrosion resistance, particularly against flowing seawater.

② Manganese White Copper: Models include BMn3-12, BMn4.0-1.5, BMn43-0.5. Manganese white copper has a low resistivity temperature coefficient, can be used over a wide temperature range, offers good corrosion resistance, and has excellent workability.

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, superior corrosion resistance, good formability in both cold and hot processing, easy machinability, and can be manufactured into wires, rods, and sheets for precision components in instruments, meters, medical devices, daily necessities, and communication fields.

④ Aluminum White Copper: Models include BAl13-3, BAl16-1.5. These are alloys formed by adding aluminum to a copper-nickel base, with a density of 8.54—0.3. The properties of the alloy are related to the ratio of nickel to aluminum content; when Ni:Al = 10:1. Commonly used aluminum white coppers include Cu6Ni1.5Al and Cul3Ni3Al, mainly used for various high-strength corrosion-resistant parts in shipbuilding, power, chemical, and other industrial sectors.
