alloy based on lead added with other alloy elements. According to performance and use, lead alloy can be divided into bearing alloy, accumulator alloy, printing alloy, mold alloy, solder alloy, cable sheath alloy, chemical corrosion resistant alloy, etc. The main alloy elements of lead alloy include Sb, Sn, Bi, Cu, Ag, etc. Antimony and tin can improve the strength and hardness of alloy. Increasing flow ability of alloy and copper can reduce segregation of alloy. Adding a small amount of silver, tellurium, smashing, and arsenic can refine the structure. Increase strength and eliminate harmful effects of impurities. Improve the corrosion resistance of alloy lead alloy has good corrosion resistance in air, sulfuric acid, fresh water and sea water. lead alloy has low melting point, good flow ability, small solidification shrinkage, and good castability. It can be used for foundry devices with complex shapes, widely used for foundry lead, lead plates, and making model for plastics and mechanical industries. lead alloy has low hardness and strength. Its tensile strength is only 30-70MPa. It is much lower than other alloy. lead alloy is easy to deform. It can be rolling and extrusion into plates, strips, bars, wires and other materials without heating.
