Tinned Wire Characteristics
The tinned wire is a product made of a bare copper wire，copper clad aluminum wire or aluminum wire as a base and uniformly coated with a tin or tin-based alloy on its surface. It meets environmental protection requirements, and has many advantages such as good oxidation resistance, heat resistance, good compactness, strong corrosion resistance, strong weldability, bright white color and so on.
Products are used for power cables, coaxial cables, conductors for RF cables, lead wires for circuit components, ceramic capacitors, and circuit boards.line.
