Abstract
A method for the production of a heat exchanger having a core part thereof formed by joining a tube of aluminum material and heat-transfer fins of aluminum material with a brazing material, which method is characterized by effecting said brazing by the use of a flux obtained by suspending a potassium fluoroaluminate complex in an aqueous solution of a pigment-forming water-soluble compound.
