ABSTRACT:
A molten aluminum alloy processing method is intended use sludge produced by the zinc phosphate treatment of structures including those of aluminum alloys effectively as a flux for molten aluminum alloy processing. The flux contains 3 to 30% by mass fluorine-equivalent metal fluorides, 40 to 90% by mass metal phosphates (8 to 18% by mass P) and 50% by mass or below inorganic salts. The sum of contents of the inorganic salts and metal phosphates is 90% by mass or below.
