The content of lead in the crust is 0.004%. It is a nonferrous metal with excellent plasticity, low strength and good corrosion resistance. Lead has great attenuation ability to vibrations, sound waves, X-rays and gamma-rays, and is grayish-black in the air. Metal lead is a good shielding material, which has great attenuation ability to X-ray, gamma-ray, acoustic wave and vibration. Its radiation protection performance is equivalent to 2.5 times thick steel plate and 6 times thick cement.
 
Lead is stable in atmosphere, fresh water and sea water. The lead oxide film attached to the lead surface can protect the internal lead from further oxidation. Lead has a good corrosion resistance to sulfuric acid, it is not resistant to nitric acid corrosion, in hydrochloric acid is not stable, but for phosphoric acid, sulfurous acid, chromic acid and hydrofluoric acid has a good corrosion resistance.
 
The combination of lead and various metals and alloys has great theoretical and practical significance. Lead is difficult to be used as structural material because of its low strength. Therefore, the bimetal made of lead and other metal materials has been successfully used. The ability of lead to absorb radioactive radiation can be used to make corresponding protective devices of various metals coated with lead.
 
Lead-based sheet composites can be used for many instruments and devices, working in ionic radiation fields, erosive media, and under strong vibration loads. For example, lead-copper or lead-aluminum Bimetallic Clad Three-Layer Plate  are needed to make devices that protect both ionic radiation and shield powerful electromagnetic fields. The radiation resistance of lead is far superior to that of conventional materials such as steel, cement, rammed earth and wood plank. But the mechanical properties of metal lead are not high, which will bring some difficulties in installation and use. Lead sheet is compounded with stainless steel or aluminum sheet by metal dynamic compounding (explosive compounding), which can protect or support the lead sheet and increase its aesthetics.

Product application:

1. Used in the fields of nuclear energy engineering, medical equipment and chemical engineering in the ionic radiation field and corrosive medium as well as under the strong vibration load for the manufacture of devices which protect the ionic radiation and shield the strong electromagnetic field at the same time.

2. Another major application of Lead Aluminium Lead Bimetallic Clad Three-Layer Plate is lead-acid battery grids and Hydrometallurgical plates. Lead has good corrosion resistance, low density, good conductivity, high strength and stiffness. There is a strong complementarity between Al and Pb. The Lead aluminium lead clad plate prepared by the two composites are excellent materials for making hydrometallurgical anode plates.
