Copper wire tin plating refers to the process of plating a thin layer of metallic tin on the surface of copper wire. Here’s why: 1. Tin plating copper wires is mainly to prevent the copper from being oxidized and forming a film - patina (chemical formula CU2(OH)2CO3) when exposed to the air. Patina has poor electrical conductivity and will increase resistance. Tinned copper wire can prevent oxidation-reduction reactions and produce patina; it can increase heat dissipation; it can improve electrical conductivity and improve wire performance. .Tinned Copper Clad Copper TCCC 2. In addition, tin plating of copper wires can also prevent the insulating rubber from becoming sticky, causing the wire core to become black and brittle, and improve its solderability. Tinned copper wire is mainly used as conductive core in rubber-insulated mining cables, flexible wires, flexible cables and marine cables, as well as as outer shielding braid and brush wire of cables.
