Study of Properties of Cu-Mn-Ni Based Brazing Material

The alloy of 34Cu-16Mn-44Ni-4B-2Si was prepared by adding small amounts of trace elements in Cu-Mn-Ni system.The design and preparation of the brazing material were introduced.The XRD and DSC analysis result showed that there is an exothermic peak at the temperature of 550℃,the adhesive strength of the alloy reaches to 386MPa which is approximately 60% of the base metal strength.
