The brass round bar, material number 2.0401, consists of approximately 57-59% copper, 2.5-3.5% lead, and the balance zinc (about 36-40%). This material is well-suited for hot forming, while higher hardness and strength can be achieved through cold working, though cold forming should be limited due to the risk of stress corrosion cracking. The brass round bar offers excellent machinability and is ideal for both soft and hard soldering. It is easy to stamp and can be mechanically polished, but not suitable for electrolytic or chemical polishing.

Evek GmbH provides brass round bars in a range of sizes at competitive prices. As a reliable supplier of CuZn39Pb3 Ms58, we offer fast and straightforward worldwide shipping.

Because of its lead content, this brass round bar has limited weldability and should not be welded by manual arc, gas, TIG, or MIG welding methods. Resistance welding is the recommended process. The 2.0401 Ms58 brass has relatively low corrosion resistance, particularly against salt solutions, organic fluids, and water.

Common applications for brass round bar CuZn39Pb3 include:

  • Fittings and tap handles
  • Screws and nuts
  • Valve bodies
  • Electrical and general mechanical engineering parts
  • Cable clamps
  • Ballpoint pen tips

Key properties of brass round steel:

  • Excellent hot formability
  • Very good machinability
  • Suitable for soft and hard soldering
  • Good stamping and mechanical polishing capabilities
  • Limited weldability (resistance welding preferred)
  • Relatively low corrosion resistance to aggressive substances like water, salt solutions, and organic liquids
