Method of brazing an aluminum alloy material and method of producing an aluminum alloy heat exchanger

摘要

A method of brazing an aluminum alloy material, which is a Nocolok brazing method of the aluminum alloy material, in which the method satisfies the condition: Ts≦̸Tf≦̸Ts+15° C. in which Tf represents an incipient fluidization temperature of a filler material, and Ts represents an incipient fluidization temperature of flux.
