Description

The present invention relates to a field for processing a metal composite material, and more particularly to an apparatus and method for continuously casting with a plurality of rollers for producing a metal coating material having high electrical conductivity.

The metal coating material having high electrical conductivity has a new structure and function formed by reliably bonding the base metal and the coating layer metal at the boundary by using a special composite technique. It has excellent overall performance and economic benefits, as it allows the properties of each component metal to function extremely well, significantly reducing its cost when applied. Typical products include copper coated with steel, copper coated with aluminum, copper coated with steel twisted pair cables, brass coated with pure copper twisted pair cables, nuclear power, automobiles, etc. A wide range of perspectives exist for applications in areas such as energy, aerospace technology, petrochemicals, marine development, and power and electronics.
