Phosphor Bronze Wire
At SMI, we manufacture phosphor bronze wires, an alloy of copper, tin and phosphorous. Our phosphor bronze wires possess excellant spring qualities, high corrosion resistance and good formability. While tin increases the strength of the material, phosphor increases its corrosion resistance and stiffness. Hence phosphor bronze, based on its varying content of tin are used in various electrical and industrial applications.
