ABSTRACT:
An aluminum material for brazing, comprising a core made of aluminum or an aluminum alloy, and a layer coated on the surface of the core. The layer is made of zinc or an alloy of zinc-and-aluminum and a brazing alloy having a melting point which is lower than that of the core by a predetermined value. The zinc or the alloy of zinc-and-aluminum and the brazing alloy have different melting points. Also disclosed are a method of manufacturing an aluminum material for brazing and a method of manufacturing an aluminum alloy heat exchanger by use of the Al material for brazing.
