copper plated aluminium sheet

Nov 25, 2022

After decades of research and practice of , many research results have been achieved in the production method of copper-aluminum bimetal plates, mainly including explosive copper plated aluminium sheet and rolled bonded copper plated aluminium sheet.

The above advantages of the explosive compound method have special advantages for the copper plated aluminium sheet in many aspects, and the use of the explosive compound method can also realize the self-cleaning of the interface, thereby greatly simplifying the production process and reducing the difficulty of compounding. However, due to the difference in initiation position, spacing, charge form and detonation wave propagation method, the composite of large-area plates can easily lead to a reduction in the recombination rate, and it is easy to produce an over-melt phenomenon at the interface, which is difficult to meet the technical requirements. Rate and unevenness to obtain higher welding quality. At present, both hot rolling and cold rolling can be used to produce copper plated aluminium sheet. On the basis of combining the pre-entry experiment, the cold rolling and hot rolling of copper-aluminum bimetal composite will be studied. Both hot rolling and cold rolling use the rolling pressure to deform and extend the two metals. The oxide layer and the pollution layer of the metal contact interface destroy the fresh metal contact and produce a combination under the action of the rolling pressure. The rolling compound method is a method of bringing two clean metal plates into contact with each other, and the metal is compounded by the pressure of the rolling mill, which is a common method for producing compound plates. It is divided into hot-rolling compound method and cold-rolling compound method. The hot-rolling compound method is to combine the reinforcement and the base material together, and then heated to a certain temperature, hot rolling to make it compound. Cold-rolled composites have developed rapidly in recent years. This method has low production costs, is suitable for mass production, and can produce products with larger lengths and widths. The common specifications of copper plated aluminum sheet produced by are as follows: Aluminum: 1060, 1100, 3003, 5052 Copper: T2 Temper: O, H12, H14, H16, H18 Copper cladding
rate: 10%, 15%, 20%, 30% Thickness range: 0.20--200mm Width: Maximum 1200mm Length: coil or sheet type.
