bedra 35600
Leaded Brass
Characteristics:
bedra 35600 is a free-machining, leaded brass alloy prized for its excellent machinability, moderate strength, good corrosion resistance in atmospheric conditions, and suitability for precision components like clock parts and engraved nameplates. It is less suitable for welding and cold working and requires care to avoid environments that promote dezincification or stress corrosion cracking.
Typical applications:
bedra 35600 is commonly used for clock and watch backs, gears, plates, nuts, appliance trim, builders hardware, hose fittings, and engraved nameplates due to its combination of strength, ductility, and excellent machinability.
