copper clad steel plate sheet

Jun 14, 2023

Copper clad steel plate sheet is a new type of material that cannot be separated by welding copper plate and steel plate through explosive clad method, explosive rolling method, etc.

The base layer is generally steel plate: Q235 series, Q345 series, 50Mn, T8, 40Cr, 16Mn, GCr15 and other materials 　
Composite boards are generally copper boards: T1, T2, T3...H96, H90, H85, H80, H70, H68, H65, H63, H62, H60... etc.
The copper clad steel plate sheet produced by explosive composite method has been widely used in petroleum, chemical, shipbuilding, electronics, electric power, metallurgy, machinery, aerospace, atomic energy and other industrial fields. The composite board is a new type of bimetal high-efficiency and energy-saving composite material with steel as the substrate and copper cladding on one or more sides. It is compounded by a special process of explosive welding. It has the corrosion resistance and wear resistance of copper. It also has good weldability, formability, extensibility and thermal conductivity of steel; copper clad steel plate sheet is now widely used in petrochemical, metallurgy, salt and alkali making, hydraulic industry, and nuclear industry.

Copper clad steel plate sheet produced by hot rolling method, after the copper and steel are surface treated, they are rolled into high-precision steel strip and high-precision copper strip by a cold rolling mill; after surface cleaning, surface residues are removed and degreasing; The cold rolling mill is rolled into a high-precision copper-steel composite strip; the copper-steel composite strip is annealed at a temperature of 650-850°C in a vacuum furnace for 1-4 hours to melt the structural molecules of the composite layer of the two metal materials , Then cool to room temperature in a vacuum furnace; combine the two strips to make the strips composite into one; finish rolling the strips; smooth and polish the composites, and divide the strips according to user requirements Package after cutting.
