In this paper, a high-temperature brazing alloy was studied. According to the conditions of use and the analysis of metallographic equilibrium diagram, the design of the alloy components. According to the melting point, wettability, corrosion resistance, mechanical properties, simulation strength test results to determine the main elements of the alloy content. The trace elements in the alloy were studied, and the content range was determined. The basic elemental content of this alloy is: 70% Mn, 25% Ni, 5% Cr, with melting point of 1050 to 1080 ° C, good machinability, can be processed into thin foil with moderate corrosion resistance in fuming nitric acid . Brazing performance of the alloy is good. Cold-rolled alloy strip in the water cracking phenomenon can be used to eliminate stress annealing and to keep the dry method to be prevented. Alloy has been stable for high temperature brazing, to meet the design and process requirements, and has been stereotyped production.
