(Summary description)There are many kinds of copper wires. The common customized bare tinned copper wire, customized tin coated copper wire and copper clad aluminum wire. The bare tinned copper wire from china is an ordinary copper wire. The process of tinned copper wire is slightly more complex than that of bare tinned copper wire from china. After the pure copper rod is pulled into wire, a thin layer of tin is plated on the surface of copper wire by hot tinning process. The appearance of this wire is silver because tin is a silver metal.
What are the differences between customized bare tinned copper wire and customized tin coated copper wire from China mainly in the following three aspects:

There are many kinds of copper wires. The common customized bare tinned copper wire, customized tin coated copper wire and copper clad aluminum wire. The bare tinned copper wire from china is an ordinary copper wire. The process of tinned copper wire is slightly more complex than that of bare tinned copper wire from china. After the pure copper rod is pulled into wire, a thin layer of tin is plated on the surface of copper wire by hot tinning process. The appearance of this wire is silver because tin is a silver metal.
What are the differences between customized bare tinned copper wire and customized tin coated copper wire from China mainly in the following three aspects:
1. Different appearance
Customized bare tinned copper wire from china is a copper wire drawn with a pure copper rod. The material is single. There is copper metal on the outside and inside, and the appearance used to be yellow; The appearance of customized bare tinned copper wire is silver because tin is a silver metal.
2. Different performance
In terms of physical properties, the customized bare tinned copper wire from china is soft and has excellent electrical conductivity; Compared with customized bare tinned copper wire,customized tin coated copper wire has good conductivity, stronger corrosion resistance and oxidation resistance, which can greatly prolong the service life of weak current cables.
3. Different processes
Customized bare tinned copper wire is copper wire drawn with pure copper rod, with single material; The process of customized tin coated copper wire from china is slightly more complicated than that of bare tinned copper wire. After the pure copper rod is pulled into wire, a thin layer of tin is plated on the surface of the copper wire by hot tinning process.
The customized tin coated copper wire from china has one more protective layer than the customized bare tinned copper wire from china, the material is also relatively soft, the conductivity is good, and the corrosion resistance and oxidation resistance are stronger.
Customized tin coated copper wire from china is mainly to prevent copper from being oxidized to form a film - Copper green when exposed to air. The conductivity of copper green is very poor, which will increase the resistance. Can increase heat dissipation; It can improve conductivity and conductor performance.
In addition, tinning of copper conductor can also prevent the insulation rubber from sticking, the wire core from blackening and embrittlement, and improve its weldability.
Customized tin coated copper wire from china is mainly used for rubber insulated mining cables, flexible wires, flexible cables and marine cables as conductive cores, as well as external shielding braids and brush wires of cables.
Customized tin coated copper wire from china has soft material and good conductivity. Compared with bare tinned copper wire from china, it has stronger corrosion resistance and oxidation resistance, which can greatly prolong the service life of weak current cables. Customized tin coated copper wire from china is easy to use and expensive. Of course, it is better to have a coating, and the coating is a mixture of silver and tin. Based on the physical and chemical properties of the coating, the main functions are as follows:
1、 The conductivity of the surface layer is higher than that of the internal copper, which is conducive to the skin effect of high-frequency AC;
2、 Because the chemical activity of silver and tin is lower than that of copper, they are not easy to oxidize and rust. Especially when used in high-temperature and humid environment, they have obvious advantages and much higher price.
