ALUMINUM ALLOY MATERIAL, FLUXLESS BRAZED STRUCTURE, AND FLUXLESS BRAZING METHOD

摘要

Provided are, in a fluxless brazing method using a Mg-free brazing material, an aluminum alloy material, a fluxless brazed structure, and a fluxless brazing method each having an excellent brazability. An aluminum alloy material is brazed, to a brazing sheet in which a core material is clad with a brazing material made of an Al-Si-based alloy having a Mg content restricted to be less than 0.10 mass%, with the brazing material without using a flux. The aluminum alloy material is made of any of an Al-Mg-based alloy containing 0.40 mass% or more and 1.30 mass% or less of Mg, an Al-Mn-based alloy, and an Al-Zn-based alloy.
