COATING MATERIAL FOR ALUMINUM ALLOY BRAZING, EXCELLENT IN MOISTURE RESISTANT BRAZING, AND ALUMINUM ALLOY PLATE FOR BRAZING, ALUMINUM ALLOY MEMBER FOR AUTOMOBILE HEAT EXCHANGER USING THE PLATE, AND AUTOMOBILE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To provide a coating material for aluminum alloy brazing, which is prevented from deterioration during the storage under a high humidity atmosphere, prevents lowering of brazing property, and is excellent in moisture resistant brazing property, and also to provide an aluminum alloy plate for brazing, an aluminum alloy member for automobile heat exchangers using the plate, and an automobile heat exchanger.;SOLUTION: In the coating material for aluminum alloy brazing, a flux powder and an oxide compound are blended, wherein the oxide compound consists essentially of silicon oxide and/or aluminum oxide and includes a micropore structure. A filler metal powder and/or an acrylic resin based binder are also blended as necessary, with the balance a solvent.;COPYRIGHT: (C)2010,JPO&INPIT
