Copper has strong corrosion resistance, beautiful appearance and color, widely used in the decorative industry
Bimetal Consists of Copper Sheet cladded on pure Aluminum Which is Base Metal alloy , both metal being diffused to form an inseparable whole by rolling bonding process. Bimetal , is therefore not and alloy and copper layers are not electro Plating but are rather mechanically welded Aluminum Plates / Sheet.

Bimetal refers to an object that is composed of two separate metals joined together. Instead of being a mixture of two or more metals, like alloys, bimetallic objects consist of layers of different metals. Trimetal and tetrametal refer to objects composed of three and four separate metals respectively.
Aluminum Copper Bimetal AND Copper Aluminum Bimetal is one and the same thing.
Copper Aluminum Bimetal consists of Copper (sheet metal) claded on pure Aluminum (Base metal) both metals being diffused together to form an inseparable whole by roll bonding process. Copper Aluminum Bimetal is therefore not an alloy and copper alloys are not electro plating but are rather mechanically welded to Aluminum sheets.
What is the process of Manufacturing Aluminum + Copper Bimetal?
Aluminium and Copper both metals being diffused together to form an inseparable whole by roll bonding process. It is mechanically welded on Aluminium with Copper sheets.
What does ROLL BONDING mean?
Roll bonding is a solid state, cold welding process, obtained through flat rolling of sheet metals. In roll bonding, two or more layers of different metals are passed through a pair of flat rollers under sufficient pressure to bond the layers. The pressure is high enough to deform the metals and reduce the combined thickness of the clad material. The mating surfaces must be previously prepared (scratched, cleaned, degreased) in order to increase their friction coefficient and remove any oxide layers. The process can be performed at room temperature or at warm conditions. In warm roll bonding, heat is applied to pre-heat the sheets just before rolling, in order to increase their ductility and improve the strength of the weld. The strength of the rolled bonds depends on the main process parameters, including the rolling conditions (entry temperature of the sheets, amount of thickness reduction, rolling speed, etc.), the pre-rolling treatment conditions (annealing temperature and time, surface preparation techniques, etc.) and the post-rolling heat treatments. The applications of roll bonding can be used for cladding of metal sheets, or as a sub-step of the accumulative roll bonding. Bonding of the sheets can be controlled by painting a pattern on one sheet; only the bare metal surfaces bond, and the un-bonded portion can be inflated if the sheet is heated and the coating vaporizes.
