Product Description

                         Bi-Metal Lead Clad Copper Bimetallic Sheet Coil Strip 

Bi-Metal Lead Clad Copper Bimetallic Sheet Coil Strip is a kind of bimetallic composite material with copper as matrix and lead as coating. Copper is a good conductive and thermal conductive material, and lead material has good corrosion resistance and radiation resistance. Lead coated copper sheet coil strip is a new type of composite material, which can be used as grid material of lead-acid batteries. Lead or lead alloys on the copper-lead composite strip can be used as active materials for batteries, copper materials as supporting materials and conductive materials, which can improve the strength of the plates, effectively reduce the internal resistance of batteries, increase the current density of batteries, reduce the heat generated by batteries, and increase the life of batteries. At the same time, the density of copper is much lower than that of batteries. The density of lead materials can effectively increase the energy density of lead-acid batteries.

Due to the high density and low strength of lead materials, it is difficult to control the process of preparing Cu-Pb composites by explosive cladding method, resulting in low yield and poor surface quality.

Bi-Metal Lead Clad Copper Bimetallic Sheet Coil Strip produced by Henan Chalco is composed of copper strip and lead clad material.China Lead Clad Copper Sheet Coil Strip can give full play to the excellent corrosion resistance of lead material and good conductivity of copper material, and solve the corrosion and conductivity problems caused by the contact between copper and strong corrosive acid solution in the battery. A special intermediate lead coating was prepared on the surface of copper strip to solve the problem of poor interfacial bonding strength between copper and lead due to the great difference of melting points between the two metals and the oxidation of metal surface. Because the copper-lead interface is well bonded, the internal resistance of the copper-lead composite strip is greatly reduced, which is beneficial to the reduction of the internal resistance of the battery.

The Bi-Metal Lead Clad Copper Bimetallic Sheet Coil Strip produced by Henan Chalco consists of copper layer and aluminum layer. The lead liquid crystallizes on the surface of the copper layer and is eventually made into copper-lead composite strip containing aluminum layer, copper layer and lead layer. The Bi-Metal Lead Clad Copper Bimetallic Sheet Coil Strip not only integrates the advantages of copper and lead, but also greatly reduces the overall density of the plate by taking advantage of the small density of aluminum. The energy density of batteries has been greatly increased. The copper strip is preferably pure copper or oxygen free copper. It is further selected as the No. two oxygen free copper brand TU2, the state is very soft, and the state code is M.
