Nickel wire is a metal wire with good mechanical strength, corrosion resistance and high heat resistance. It is suitable for making vacuum devices, electronic instrument components, and filters for strong alkali in chemical production.

Its mechanical properties are close to those of carbon steel, and its resistance to alkaline corrosion is second only to silver among metal materials. A black protective film will form on the surface of nickel wire in concentrated alkali, making it very corrosion-resistant. It is mostly used for electric light source materials and coatings. It has high surface quality and good processing performance. It is used to make work such as anodes, diaphragms, electrode brackets, etc. It can also be used as a guide wire in light bulbs. In addition, it plays a very important role in the chlor-alkali industry. Electrode materials have alloys of various components due to different use conditions. Moreover, electrode materials are required to have low resistivity to avoid overheating of electrodes, high high temperature strength to reduce material wear, and more viscous melting and volatilization under the action of arc to improve service life.
Advantages of nickel wire: ● Weldability, high conductivity, and suitable linear expansion coefficient ● Good strength at high temperature and low resistivity
