摘要： An arc brazing method of bonding different materials includes disposing an aluminum alloy to be bonded on a steel base material and arc brazing a welded portion between the steel base material and the aluminum alloy using a wire. The wire is an alloy containing Zn. It is possible to compensate for brittleness due to the bonding of different materials and to improve wettability.
