The brass round bar with the material number 2.0401 consists of approximately 57–59% copper, 2.5–3.5% lead, and 36–40% zinc. This material is easy to hot form and achieves high hardness and strength through cold forming, though its cold formability is limited due to stress corrosion cracking. It offers excellent machinability and is ideal for both soft and hard soldering. Brass CuZn39Pb3 round bars are suitable for mechanical polishing and stamping, but not for electrolytic or chemical polishing.

Evek GmbH supplies brass round bars in various sizes at competitive prices. As an experienced supplier of CuZn39Pb3 Ms58, we ensure smooth worldwide shipping.

Because of its lead content, this brass bar has limited weldability. It should not be welded using manual arc, gas, TIG, or MIG welding methods. Resistance welding is most appropriate. The 2.0401 Ms58 material has relatively low resistance to corrosion, particularly against salt solutions, organic liquids, and water.

Typical applications for brass round bar CuZn39Pb3 include:

  • Fittings and tap handles
  • Screws and nuts
  • Valve bodies
  • Parts for electrical and general mechanical engineering
  • Cable clamps
  • Ballpoint pen tips

Main features of brass round steel:

  • Excellent hot formability
  • Outstanding machinability
  • Suitable for soft and hard soldering
  • Good for punching and mechanical polishing
  • Limited weldability (resistance welding recommended)
  • Low corrosion resistance to aggressive substances (water, salt solutions, organic liquids)
