Problems solved by technology

[0002] The chemical stability of nickel metal in nature is high. Pure nickel wire has the characteristics of good strength and low resistivity under high temperature conditions. It is widely used in radio, electric light source, machinery manufacturing, chemical industry and other fields. The conductive wire is made of nickel wire as the main body, and a layer of metal coating is coated on the outside of the nickel wire. The ordinary nickel wire coating has low corrosion resistance and poor color resistance, and is easy to break during welding. In addition, the common metal coating The uniformity of thickness is poor, and the continuity cannot meet the requirements of special electrical products, which may easily cause damage to some electronic product accessories, seriously reduce the service life of the product, and cause economic losses to manufacturers and users.
