Title:
BRAZING MATERIAL FOR BRAZING HEAT-EXCHANGER ALUMINUM PIPE, METHOD FOR JOINING HEAT-EXCHANGER ALUMINUM PIPE USING SAME, AND JOINT STRUCTURE OF HEAT-EXCHANGER ALUMINUM PIPE
Document Type and Number:
WIPO Patent Application WO/2017/073003
Kind Code:
A1
Abstract:
A brazing material for brazing a heat-exchanger aluminum pipe according to the present invention is formed as a wire rod containing an alloy base material containing aluminum and zinc and a flux with a melting point lower than that of the alloy base material. When the alloy base material is defined as 100 mass%, the content of the zinc in the alloy base material ranges between 40-75 mass%, the content of the flux ranges between 10-25 mass%, and the flux is contained in the alloy base material. Thus, aluminum pipes can be joined together efficiently with good quality.
