The conductor material of the wire can usually be divided into bare copper, tinned copper wire, nickel plated copper wire, etc., so what is the impact of these different conductors?
The conductor material of the wire can usually be divided into bare copper, tinned copper wire, nickel plated copper wire, etc., so what is the impact of these different conductors?
1. bare copper: bare copper refers to pure copper conductor in the industry, that is, the copper surface can be processed without any research on the impact of the coating. under normal development, the copper content in oxygen-free copper is> 99.97%, and the copper content of low-oxygen copper is> 99.95%. Bare copper wire is a common wire for analysis and processing of pure copper conductor materials. The conductive wire is strong, and the stability of the signal data transmission system is very strong. Bare copper shielding is our * good conductor except gold shielding. The price is relatively cheap, easy to oxidize, better on tin, the price is relatively simple and cheap.
2. tinned copper wire: refers to the surface coated with a layer of metal tin copper. Tin plating prevents copper from forming when exposed to air-a thin film of copper whose conductivity increases resistance. Although tin is not an inert metal and is more active than copper, it is very stable in air at room temperature because the surface of tin will produce a tight oxide film that prevents the continuous oxidation of tin. Therefore, tin plating on the surface of copper can improve the oxidation resistance of copper to a certain extent. Tinned copper has good stability, conductivity, wear resistance, corrosion resistance, electromagnetic shielding performance, has a good application prospect. Its tin is good, the price is cheap, but the temperature resistance is generally general, usually only can reach 150 ℃, in the conductor diameter is greater than the 0.38 can reach 200 ℃.
3. nickel-plated copper wire: the stability of nickel-plated copper wire in the air is very high, which can improve the wear resistance of the surface of the product. It has the advantages of excellent abrasion resistance, corrosion resistance, weldability and high hardness, which can meet the technical requirements of different parts and improve the service life of the workpiece. The temperature resistance can reach 250 ℃, but it is not good for tin, the price is more expensive, and the conductivity is poor.
