Ideal for applications requiring elasticity, abrasion resistance, and conductivity. For connectors, switches, relays, etc.
Phosphor bronze is a copper alloy primarily used in electrical and electronic components as contacts and conductive terminals. It is an alloy made by adding tin and a small amount of phosphorus to copper, resulting in a material with excellent spring properties and adjustable hardness and workability depending on the amount of tin and the finishing treatment. It is used in numerous products, particularly in electronic components, such as connectors, switches, and relays, where repeated operations and contact points are involved. As a copper alloy, it encompasses essential properties required for electrical and electronic components, including wear resistance, high strength, high heat resistance, and springiness, making it one of the important materials supporting modern society. Phosphor bronze is chosen for its price, performance, and availability, as well as its long-standing track record and reliability. Our company stocks standard sheets and round bars of phosphor bronze. We have a particularly rich lineup of phosphor bronze, including spring phosphor bronze in addition to the standard variety.
