The paper gives results of investigations of a set of properties of the brazed joints on a copper alloy strengthened by dispersed particles of Al2
, produced by vacuum brazing using adhesion-active brazing filler metals. It is shown that application of heat treatment of the base metal in combination with filler metal of the Cu-Ti system ensures tensile strength of the brazed joints at a level of 81 % of that of the as-received base metal, and 92 % of that after preliminary heat treatment.
