Silicon brass and lead brass are well‑known free‑machining copper alloys. Lead improves chip breaking while silicon enhances strength and wear resistance, making them perfect for high‑speed CNC turning.

For mass production of bolts, nuts, valve cores, pipe fittings and general hardware, these brasses reduce tool wear and shorten cycle time. Manufacturers gain higher output and lower processing cost per piece.

Different grades balance machinability, strength and corrosion resistance. Lead brass offers the best cutting performance, while silicon brass is chosen when higher mechanical strength is required.

We keep various brass rods and profiles in stock. Custom cutting and pre‑machining services help buyers receive semi‑finished parts ready for final assembly.
