The paper presents results of investigations of copper and brass Joints made using silver powder with less than 1 цш particle size as the braze alloy. Explanation is given of abnormally high formation rate of the seam melt of eutectic composition in brazing. Application of powders with higher degree of dispersity has good prospects for Joining structural materials for which heating temperature is critical.
Keywords: brazing, powder braze alloy, silver, dispersity, brazing temperature, process activation
