BRAZING METHOD IN SHORT TIME FOR ALUMINUM ALLOY ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a brazing method in a short time for an aluminum alloy assembly, by which a heating time for brazing is remarkably shortened. SOLUTION: This is the brazing method for the aluminum alloy assembly by using a brazing filler material alloy whose liquidus temperature is 540 deg.C or below and a difference in temperature between the liquidus temperature and a solidus temperature is 100 deg.C or below. A maximum arrival temperature in the assembly in the case of heating by brazing, is made higher than liquidus temperature by 40 deg.C or over and is made to 585 deg.C or below.
