Tinned copper clad steel wire, commonly known as: tinned iron wire, referred to as: tinned CP wire, mainly used for electronic component leads, PCB board jumpers, electronic guide pins; it is based on low carbon steel core wire, annealed Softened to soft steel wire, after electroless plating of copper layer, hot dip immersed in lead-free tin-based alloy; its production cost is relatively low, it is the best substitute for tinned copper wire.

Features: High strength and toughness of steel: high rigidity, easy to cut and form, in the process of assembly flow, can stand on its own without dumping, adapt to the production automation of RC components. In the case of the same elongation, the tensile strength is much higher than that of the copper wire, and the coefficient of linear expansion is also small. Has high conductivity and good bending performance. Has good solderability. Has good magnetic permeability. Has excellent high frequency characteristics. At high frequencies, the skin effect increases with increasing frequency, and the electrical conductivity of the wire can be compared to copper wires of the same cross section. It has excellent aluminum welding characteristics and good wire butt welding processability. Save a lot of copper and reduce the cost of lead wires for electronic components.
