Tinned Copper Clad Steel wire Tinned copper-clad steel wire is what we often call "CP" wire. Tinned copper-clad steel wire uses low carbon steel as the core wire, is evenly coated with an oxygen-free copper layer using mechanical methods, and then is plated with a pure tin layer. New composite materials. Due to the high purity of materials selected for each coating (plating) layer, the tightness between the copper coating layer and the tin plating layer is good. Generally divided into two types: soft state (A) and hard state (H).Tinned Copper Clad Steel TCCS Application areas: It is widely used in leads and jumpers of electronic components and core wires of radio frequency cables, and has become an ideal wire in the communications, electronics, and power industries.
