Abstract Nuclear fusion is a new source of energythat humanity is exploring and has made certain progress. Currently, plasma-facing components suffer from high performance requirements and difficult connections. This paper discussed the current status and development trend of brazing technology for plasma-facing materials and copper alloys. The brazed joints between CuCrZr alloy and three kinds of plasma-facing materials, such as C/C materials, tungsten and beryllium, are introduced respectively, and the joints under different types of brazing materials and brazing processes are presented. The improved optimization of the three materials during their development to accommodate higher power tokamak devices is clarified, and the important role of brazing technology in the development of the fabrication of the first wall is pointed out. Finally, an outlook is given for heterogeneous material joining applied in first-wall devices.

Key words： brazing plasma-facing material copper heterogeneous material
