Tinned Copper Clad Aluminum TCCA,[Reasons for tin plating of copper wires] Tin plating of copper wires refers to the process of plating a thin layer of metallic tin on the surface of copper wires. Tin plating copper wires is mainly to prevent the copper from being oxidized when exposed to the air to form a film - patina (chemical formula CU2(OH)2C03). Patina has poor electrical conductivity and will increase resistance. Tinned copper wire can prevent oxidation-reduction reactions and produce patina, which can increase heat dissipation, improve electrical conductivity, and improve wire performance.Tinned Copper Clad Steel TCCS

In addition, tin plating 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.Tinned Copper Clad Copper TCCC
