C17500 beryllium copper round rod with highly corrosion-resistant and highly conductive

C17500 beryllium copper rod is a high-performance copper alloy material, presenting a standard cylindrical shape. It can also be customized into square rods, hexagonal rods and other irregular cross-sections according to customer requirements. Its main components are copper (Cu) and a small amount of beryllium (Be, with a content of approximately 0.2% to 0.6%), supplemented by trace elements such as nickel and cobalt. After solution treatment and aging strengthening, it possesses excellent comprehensive properties. C17500 beryllium-copper rod has high strength, high conductivity (up to 45%–50% IACS) and good thermal conductivity. At the same time, it also has excellent fatigue resistance, corrosion resistance and non-magnetic properties. This material can maintain stable performance in high-temperature or high-stress environments and is widely used in electronic connectors, relay spring clips, switch contacts, mold inserts and aerospace precision components, etc. Due to its strong machinability, it is easy to be turned, milled and cold-drawn formed, and has good dimensional stability after heat treatment. It is an ideal alternative to traditional phosphor bronze or stainless steel in high-end manufacturing. C17500 beryllium-copper rod complies with international standards such as ASTM B194 and AMS 4535, meets the high requirements of the industrial environment for the reliability and lifespan of the material, and is a key basic material for improving product performance and market competitiveness.
