The brass round bar with material number 2.0401 is an alloy consisting of copper (approx. 57-59%), lead (approx. 2.5-3.5%), and the remainder zinc (approx. 36-40%). This material is easy to hot form, and achieves high hardness and strength through cold working, though its cold formability is limited due to the risk of stress corrosion cracking. Brass round bar also offers excellent machinability and is suitable for both soft and hard soldering. It is ideal for stamping and can be mechanically polished, but not chemically or electrolytically.

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

Due to the lead content, brass round bar has limited weldability. It is not suitable for manual arc, gas, TIG, or MIG welding. Resistance welding is the preferred method. Brass round material 2.0401 Ms58 has relatively low corrosion resistance and is not recommended for use with various salt solutions, organic liquids, or 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

Key properties of brass round bar:

  • Excellent hot formability
  • Very good machinability
  • Suitable for both soft and hard soldering
  • Good for stamping and mechanical polishing
  • Limited weldability (resistance welding is best)
  • Relatively low resistance to corrosive media such as water, salt solutions, and organic liquids
