Effect of the composition of brazing alloys of the copper–phosphorus–antimony system on the structure and properties of copper alloys

Abstract

Results of investigations of the near-eutectic region of copper–phosphorus–2% antimony alloys and of the structure and properties of alloys are presented. The eutectic composition of the alloy is determined, the behaviour of hypoeutectic and hypereutectic alloys is investigated and the application of the hypereutectic optimum composition for obtaining high technological properties of the brazing alloy and quality of brazed joints is described.
