Copper Alloy No. 852 is a free-machining copper-zinc-lead-tin alloy for castings. It is a relatively low-cost alloy with good machining and polishing characteristics and a pleasing yellow color. Having only moderate strength, it is used in a wide range of light-duty applications such as bushings, valves and plumbing goods. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-362. Producer or source: Copper alloy foundries.
