Product description

Tin plated copper stranded wire has excellent corrosion resistance, heat resistance, and weldability

Outer diameter not exceeding tolerance, high conductivity, performance meets multiple standards

detailed description:

Tin plated copper stranded wire adopts electrolytic tin plating process, and multiple strands are drawn simultaneously in production. The drawing process adopts continuous annealing process, and the multiple strands of stranded wire do not jump or back. The product has a uniform appearance, beautiful luster, and excellent industrial characteristics such as corrosion resistance, heat resistance, and weldability. The conductor is tightly pressed, the outer diameter of the wire harness does not exceed the tolerance, and the high conductivity performance. The various properties of tin plated copper stranded wire can meet the requirements of DIN40500 (German Industrial Standard) and ASTMB33 (American Society for Testing and Materials).

The specifications of tinned copper stranded wire, such as wire diameter, tin plating thickness, and hardness, can be specified according to customer requirements. And ensure the continuity, adhesion, uniformity of thickness, and brightness of the tin layer

The copper rods used for the raw materials of tinned copper stranded wire are all produced using the 350000 ton SCR-7000 copper continuous casting and rolling production line of the US South Line. The single wire uses the most advanced high-speed continuous pulling and copper withdrawal drawing process in China. The entire processing of copper stranded wire is controlled by a microcomputer, and the quality of the single wire is stable and reliable. The performance of tinned copper stranded wire meets or exceeds national standards and EU electrical standards.
