ANACONDA Alloy 482 is a variation of the basic Naval Brass composition; it contains a small amount of lead (nominally 0.70%) to improve its machinability. It has good mechanical properties and high resistance to corrosion by seawater. It is used for marine hardware, valve stems and other machined parts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-452. Producer or source: Anaconda American Brass Company.
