The brass round bar, material number 2.0401 (CuZn39Pb3), is made of approximately 57-59% copper, 2.5-3.5% lead, and the remainder zinc (36-40%). This material is easily hot formable, and its hardness and strength are improved through cold forming, though cold formability is somewhat limited due to possible stress corrosion. Brass round bar is highly machinable and suitable for both soft and hard soldering. It can be mechanically polished but is not suitable for electrolytic or chemical polishing.

Evek GmbH offers brass round bars in various sizes at competitive prices, ensuring fast and reliable worldwide shipping as a trusted supplier of CuZn39Pb3 Ms58.

Due to its lead content, welding options for this brass bar are limited. It should not be welded by manual arc, gas, TIG, or MIG welding methods. Resistance welding is the most suitable option. The 2.0401 Ms58 alloy also has relatively low corrosion resistance and is not resistant to certain salt solutions, organic liquids, or water.

Typical applications of CuZn39Pb3 brass round bar include:

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

Key characteristics of this brass round bar:

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