Abstract

See full text

A method for manufacturing an aluminum product includes a spraying step, in which a workpiece heated at a brazing step is cooled by spraying of a process liquid on the workpiece, as a boehmite treatment step after the brazing step. After the brazing step, the workpiece has been heated for brazing. A surface of the workpiece can be changed into boehmite having corrosion resistance by the spraying of the process liquid on the heated workpiece so as to contact a water molecule. Moreover, the process liquid sprayed can be dried by the heat of the workpiece. Accordingly, the brazing step, a surface treatment step and a drying step can be performed in a consecutive line.
