Huge technological progress in high-temperature brazing has made in the last few decades. This chapter reassesses the topic. It describes compositional and structural specifics of base metal (BM) classes at high temperatures. The classification of brazing filler metals (BFMs) is given, with some new compositions. In choosing optimal BFMs the metallurgical background is built on phase diagrams of BM and BFM and potential interactions. Novel methods of BFM placements, joint loading and heat treatment are covered. Rapidly solidified amorphous BFMs are described. The modern outlook on metallurgical paths of joint formation and an understanding of brazing mechanisms are provided. Finally, recent examples of advanced applications are given, particularly in the aerospace and automotive industries and in energy conservation and environment protection.
