Brass round bar CuZn39Pb3 (material number 2.0401) is an alloy made from approximately 57-59% copper, 36-40% zinc, and 2.5-3.5% lead, with small amounts of other elements. This material is known for its excellent machinability and is easy to hot form. It achieves high hardness and strength through cold working, although its cold formability is limited due to the risk of stress corrosion cracking. Brass round bar is suitable for both soft and hard soldering, and can be stamped and mechanically polished. However, it is not recommended for electrolytic or chemical polishing. Due to its lead content, welding options are restricted; resistance welding is the preferred method, while manual arc, gas, TIG, and MIG welding should be avoided. The corrosion resistance of this brass grade is relatively low, especially when exposed to water, salt solutions, or organic liquids. Typical applications for brass round bar CuZn39Pb3 include fittings, tap handles, screws, nuts, valve bodies, electrical and mechanical components, cable clamps, and ballpoint pen tips. Key properties: - Excellent hot formability and machinability - Suitable for soft and hard soldering - Good for punching and mechanical polishing - Limited weldability (resistance welding recommended) - Relatively low resistance to aggressive media The material is available in various sizes and is kept in stock for quick dispatch. Please note, length tolerances are +/-2mm and the ends of sawn bars may be sharp or not deburred. For other sizes or steel qualities, contact us for a custom offer.
