what is copper clad aluminum？

Jan 01, 2023

Copper clad aluminum is a new type of material that uses various composite technologies to achieve metallurgical bonding between the copper interface and the aluminum interface. Copper-aluminum composite materials have the advantages of copper: electrical conductivity, good thermal conductivity, easy welding, low contact resistance, easy electroplating, and beautiful appearance. At the same time, it also has the characteristics of low price, light weight, excellent heat dissipation performance and economy of aluminum.

Copper clad aluminum is a new type of material that cannot be separated from copper plate and aluminum plate through cold rolling, hot rolling, explosive clad method, explosive rolling method and other methods.
Hot rolling method: This method mainly rolls copper-aluminum composite thick plates
Cold rolling method: This method mainly rolls copper-aluminum composite sheet
Explosive compounding method: The compounding speed in this way is very fast, it is completed in an instant, and the bonding strength is high. It produces copper-aluminum composite thick plates.

Explosive rolling method: This method can produce copper-aluminum composite thin plates. First, the rolling blank is produced by the explosive composite method, and then the thin plates are rolled by rolling.
The mainstream process of copper-aluminum composite board is: explosive compounding method, explosive rolling method.

Application field of copper clad aluminum plate sheet

Copper clad aluminum plate sheet has been widely used in petroleum, chemical, shipbuilding, electronics, electric power, metallurgy, machinery, aerospace, atomic energy and other industrial fields.
