High Quality Metal Ingot Lead Scrap by Lead Product Supplier

Lead is the raw material for manufacturing batteries, cables, bullets and ammunition, as well as the additive of gasoline. Lead compounds are used as raw materials for pigments, glass, plastics and rubber. Because metal lead has excellent acid and alkali corrosion resistance, it is widely used in manufacturing chemical and metallurgical equipment. Lead alloy is used as bearing, movable type gold and solder. In addition, lead has also opened up some new uses. For example, it is used as a stabilizer of asphalt to prolong the service life of pavement; It is used for manufacturing shielding and nuclear waste storage tanks in nuclear power plants, high-power battery packs for load adjustment in electric power departments, and magnetic fluid dynamics devices.

Lead forms a dense lead oxide film on the surface of the air, a lead carbonate film in the humid air containing carbon dioxide, and a lead sulfate film in sulfuric acid, which play a good protective role. Therefore, lead has excellent corrosion resistance in many media, especially in sulfuric acid. The corrosion rate in the atmosphere of lead industrial area is 0.00043~0.00068mm/a; The corrosion rate in natural seawater is 0.01~0.015mm/a; When the concentration of sulfuric acid is as high as 70% - 80% and the temperature is 50 ℃, lead still has good corrosion resistance.
