Product parameter

Chemical composition
The chemical composition of B0.6 white copper mainly consists of nickel + cobalt (Ni+Co: 0.57 - 0.63%), iron (Fe: 0.005%), copper (Cu: the remainder), and trace impurities such as silicon, lead, sulfur, carbon, and phosphorus, with the total impurity content not exceeding 0.1%.
‌Detailed Chemical Composition Explanation‌
B0.6 white copper is a copper-based alloy with nickel as the main additive element. Its standard chemical composition is as follows:‌
‌Main Components. Nickel + cobalt (Ni+Co): 0.57% - 0.63%.
Copper (Cu): the remainder (typically over 99%).
‌Trace Elements. Iron (Fe): ≤ 0.005%.
Silicon (Si): ≤ 0.002%.
Lead (Pb): ≤ 0.005%.
Sulfur (S), carbon (C), phosphorus (P): all ≤ 0.002%.
‌Total Impurity Content‌: ≤ 0.1%.‌
‌Data Source and Authority‌
The test data from Baidu Academic (2024) and Chemical Industry Network (2025) are consistent. The nickel and cobalt content is clearly stated as 0.57% - 0.63%, while some earlier materials (such as 2011 Metal Materials Science) have differences in expression (such as nickel content 25%), which may be incorrect labeling for other grades of white copper.‌
The limits for trace elements are based on the latest published process performance analysis (2024), where the content requirements for elements such as iron, silicon, etc. are more stringent.‌
‌Characteristic Correlation‌
The B0.6 white copper with low nickel content has excellent electrical resistance and thermoelectric properties, suitable for the electrical engineering field. Its composition design takes into account both conductivity and corrosion resistance.‌
