Abstract
Provided is a brazed aluminum member brazed with a member formed of a brazing sheet, in which two or more grooves are provided on a surface of the brazed aluminum member in a fillet forming area, a groove depth (D1) of the grooves is 0.005 mm to 0.50 mm, a groove width (W1) of the grooves is 0.005 mm to 0.50 mm, a ratio (W1/D1) of the groove width (W1) to the groove depth (D1) is 10.00 or less, and a space (P1) between adjacent grooves is 0.00 mm to 0.30 mm. The present invention provides an aluminum alloy material and a method for manufacturing a brazed body that can secure good brazing properties even when the clearance between the jointed members is large in the case where the aluminum material is brazed without using a flux.
