Description

2.0372 (CuZn39Pb0.5) is a leaded Muntz metal, based on the same 60/40 copper zinc alloy structure as CZ109 (CW509L), with a fine dispersion of lead particles. This grade offers very good hot working properties and is more readily machined than the non-leaded CZ109 (CW509L). The alloy also features good strength, ductility and general corrosion resistance and is ideal for components that require hot forging or upset forging followed by machining. It shows the following features and properties:

Good strength and ductility

Hot formability and machinability
