Tinned Copper Wire

The process of tinned copper wire is slightly more complicated than bare copper wire. The pure copper rod is drawn into wire and then a thin layer of tin is plated on the surface of the wire using a hot tinning process. The appearance of this wire is silver, because tin is the reason for the silver metal. Tinned copper wire, the material is relatively soft, good electrical conductivity, compared with bare copper wire, its corrosion resistance, oxidation performance is stronger, can greatly extend the service life of weak electrical cables.

Tinned copper wire is a wire material with excellent electrical conductivity and corrosion resistance. It is made by coating the surface of copper wire with a layer of tin.

Tin plating enhances the corrosion resistance of copper wire to some extent because tin forms a dense oxide layer that prevents oxidation and corrosion. In addition, the addition of tin improves the solderability and reliability of the copper wire.

Copper wire tinned can also avoid the insulation rubber sticky, black core brittle, and improve its solderable function.

　　Tinned copper wire is mainly used for rubber-insulated mining cables, flexible wires, flexible cables and marine cables as conductive cores, as well as the outer shield of the cable weaving layer and brush wire.

　　Tinned copper wire, the raw material is relatively soft, conductive function is outstanding, compared with bare copper wire, its corrosion resistance, anti-oxidation function is stronger, can greatly extend the service life of weak power cable. Tinned copper wire is good, expensive. Of course, there is a coating is good, and coated with a silver-tin mixture, according to the physical and chemical properties of the coating, the primary function of two points:

　　First, the surface conductivity is higher than the internal copper, which is conducive to high-frequency communication skin effect.

　　Second, because the chemical activity of silver and tin is lower than copper, not easy to oxidation and rust, especially when used in high-temperature humid environment, the superiority of the appropriate significant, the price is also much higher. As for home use, in fact, this wire is generally suitable for high-power high-frequency current transmission, in the 220v50Hz occasions are classified as large materials and small use. Tinned copper wire is widely used in electronics, communications, automotive and other fields, such as cables, connectors, electronic components, etc.. Its excellent performance makes it an essential part of many electronic products.
