Patent ID: 10307869

Abstract:
The present invention provides an aluminum alloy brazing sheet for electric resistance welding, which has high strength while being thinned and can reduce the occurrence of welding defects in the electric resistance welding. Disclosed is an aluminum alloy brazing sheet for electric resistance welding, including a core layer and a brazing filler layer cladded on at least one surface of the core layer, wherein the brazing filler layer is made of an aluminum alloy comprising Si: 5.5 to 12.0% by mass, and at least one of Na: 0.0003 to 0.0030% by mass and Sr: 0.0020 to 0.1000% by mass, with the balance being Al and inevitable impurities, wherein the brazing filler layer in a molten state at 650° C. exhibits a viscosity of 0.01 Pa·s or less.
