Aluminum alloy material, fluxless brazed structure, and fluxless brazing method

摘要

PROBLEM TO BE SOLVED: To provide an aluminum alloy material having excellent brazing property, a fluxless brazing structure, and a fluxless brazing method in a fluxless brazing method using an Mg-less brazing material. An aluminum alloy material is a brazing sheet obtained by clad a brazing material made of an Al—Si alloy regulated to Mg: less than 0.10% by mass on a core material, and the brazing material is used without using flux. From any of Al-Mg-based alloys, Al-Mn-based alloys, and Al-Zn-based alloys, which are brazing aluminum alloy materials and contain Mg: 0.40% by mass or more and 1.30% by mass or less. Become.
