Brass rod with the material number 2.0401 consists of copper (approx. 57-59%), lead (approx. 2.5-3.5%) and a remainder of zinc (approx. 36-40%). The material 2.0401 is good for hot forming, but high hardness and strength of the grade are achieved through cold forming. However, the cold formability itself is limited due to the risk of stress corrosion cracking. Brass round material also has very good machinability and is well suited for soft and hard soldering. Brass round steel CuZn39Pb3 is easy to stamp and can only be mechanically polished (not suitable for electrolytic or chemical polishing).
Due to the lead content, brass round steel can only be welded to a limited extent. The material cannot be welded using the following welding methods: manual metal arc welding, gas welding, TIG and MIG welding. Resistance welding is best suited for welding the grade. Brass round material 2.0401 Ms58 has a relatively low corrosion resistance. In particular, it is not resistant to various salt solutions, organic liquids and water.
Brass round bar CuZn39Pb3 is often used in the following areas:
Brass round steel is characterized by the following properties:
