Roll cladding

Roll cladding is a process in the metalworking industry that is used to finish the surface of metal products. It is a process in which metal sheets are passed through rollers, whereby a thin layer of another metal is applied to the surface of the base metal.

The purpose of roll cladding is manifold. On the one hand, it makes it possible to improve the aesthetic properties of the surface, as the applied metal provides a shiny and uniform texture. On the other hand, roll cladding can also be used to increase the corrosion resistance and hardness of the surface. This makes the process particularly attractive in industries such as the automotive industry, electronics and jewelry manufacturing.

The roll cladding process begins with the base metal, often in the form of sheets or strips, being passed between two rolls. The cladding material is placed between the rollers and transferred to the surface of the base metal. The rollers generate high pressure, which bonds the two metals together and creates a homogeneous surface.

The choice of materials for the base metal and the cladding material depends on the desired properties of the end product. Typical combinations include copper-over-steel, stainless steel-over-aluminum or other metallic combinations.

Roll cladding thus offers an efficient way to improve the material properties of metal products while meeting aesthetic requirements. It is a process that is used in various industries and helps to manufacture products with improved performance characteristics.
