Abstract
A brazing, monolayer, aluminum-alloy material has a chemical composition composed of Si: 1.5 mass % or more and 3.5 mass % or less, Fe: 0.05 mass % or more and 2.00 mass % or less, Mn: 0.1 mass % or more and 2.0 mass % or less, Mg: 0.005 mass % or more and 0.500 mass % or less, and Bi: 0.010 mass % or more and 0.500 mass % or less, the remainder being Al and unavoidable impurities; and has a metallographic structure in which Mg—Bi-series compounds are dispersed in an Al matrix. The surface-area ratio of the above-mentioned Mg—Bi-series compounds in any arbitrary cross section is 0.05% or more.
