Take the processing of a magnetic functional component as the background, the integrative process of vacuum brazing and heat treatment for 1 J22 and 0 Cr18 Ni9 with BNi2 filler metal was studied. Through the metallographic, energy spectrum and magnetic properties analysis, the effect of the integrative process on the connection and magnetic properties of the component was analyzed. The results show that the BNi2 filler metal has excellent wettability to the two base metals. The surface of brazing seam is bright and the structure is compact. The grain of the 1 J22 alloy grows and homogenizes, and the magnetic properties are optimized and meet the requirements. The integrative process can stabilize quality, improve efficiency,save energy and reduce production cost. It can be extended to the processing of all magnetic functional components.
