Title:
BRAZING MATERIAL FOR AL AND BRAZING METHOD
Document Type and Number:
Japanese Patent JPS6068188
Kind Code:
A
Abstract:
PURPOSE: To obtain a brazed part having high joining strength in a nonoxidative atmosphere by adding a prescribed amt. of P to an Al-Si system.
CONSTITUTION: A brazing material for Al contg., by weight, 5W13% Si and 0.004W<0.08 P and consisting of the balance Al is used. Al is brazed by using such brazing material for Al without flux in a nonoxidative atmosphere having ≤-20°C dew point or in the atmosphere into which the nonoxidative atmosphere gas having ≤-20°C dew point is fed under the reduced pressure. Since the soldering material has good wettability with Al or Al alloy, the brazed part having high joint strength is obtd. in the nonoxidative atmosphere having ≤-20°C dew point.
