Abstract
The invention provides composite materials for aluminium base brazing. The composite materials comprise aluminium or aluminium alloy base materials, and a coating arranged on the base materials, wherein the coating comprises metal powder for brazing, brazing flux and thermoplastic methyl acrylic ester copolymers. According to the composite materials, the thermoplastic methyl acrylic ester copolymers serve as carriers to load the metal powder and the brazing flux and can volatilize or can be thermally decomposed before the brazing flux is melted, no residues exist, and influences on the brazing cannot be caused. In the brazing process, the brazing flux can eliminate oxides on surfaces of aluminium products, so proceeding of the brazing process is benefited. The metal powder is melted and exposed on the surfaces of aluminium products in the brazing process, the fact that the appropriate liquidus temperature promotes excellent brazing is guaranteed, and corrosion resistance in brazing positions is also improved because of existence of the metal powder. Therefore, the composite materials for the aluminium base brazing do not need to use a great amount of fluoride brazing flux, and has good brazing effects.
