Title: Manufacture of aluminum material for brazing and brazing method
Inventor: SAITO MASAJI
IPC: B23K35/22
Filed: 1993-12-27
Abstract: PURPOSE:To avert the problem of brazing of a non-corrosive oxide flux by treating an aluminum material for a specific time at a specific temp. with an aq. soln. contg. a potassium fluoride of a specific concn. CONSTITUTION:The aluminum for brazing is produced by treating the aluminum material for 1 second to 20 minutes at 5 to 70 deg.C with the aq. soln. contg. the potassium fluoride of the concn. of 0.01 to 40%. An potassium fluoride compd. film is formed on the surfaces of the aluminum material. For example, oxidation prevention is inferior if the thickness of the film is below 0.001mum. The effect is not expected even if the film exceeding 0.5mum is formed. There is no need for unduly incorporating a getter material into a brazing filler metal in vacuum brazing. Vacuum brazing is possible even if an Al-Si brazing filler metal without contg. Mg at all or contg. just <0.5% Mg is used.
