L. Klein Bronze 3444 is a wrought copper-tin-lead-zinc-phosphorus alloy. The addition of tin increases its corrosion resistance and strength, while the addition of phosphorous increases wear resistance and stiffness. L. Klein Bronze 3444 combines high strength and fatigue resistance with high wear resistance, good machinability, and good corrosion resistance. 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-939. Producer or source: L. Klein SA.
