CuNi2/CuNi6/CuNi8/CuNi10 /CuNi44 Copper Nickel CuNi Alloy Electric Heating Wire With Low Resistance
Product Introduction
CuNi wire has a wide range of applications in the chemical and petroleum industries, mainly due to its excellent corrosion resistance and good mechanical properties. This alloy can remain stable in high temperature and corrosive environments, and is suitable for manufacturing components such as pipes, valves and reactors that need to withstand corrosive media. The corrosion resistance of CuNi alloy is particularly outstanding, especially in saline, acidic and alkaline environments, and can effectively resist pitting and crevice corrosion. This feature is mainly due to the addition of nickel, which forms a strong solid solution structure with copper, allowing a dense passivation film to form on the surface of the material, thereby preventing further erosion by corrosive media. In addition, CuNi alloy also has good anti-biofouling properties, which can effectively prevent biological attachment in marine environments and reduce maintenance costs. In the oil and gas industry, CuNi wire is also used to manufacture pipes, valves and bushings exposed to corrosive liquids and harsh environmental conditions. It can resist oxidation and corrosion at the same time, ensuring reliability and safety on the seabed and offshore drilling platforms.
