Modern industrial technologies can not be realized without materials, providing creation of brazed joints with high performance characteristics (such as corrosion and radiation resistance, and mechanical strength), ecological purity of the process, and methods for their disposal. This paper presents the main results of development and production of rapidly quenched belt-type filler metals in amorphous and nanocrystalline states, based on Al, Cu, Ni, Fe, Ti and Zr (STEMET) and designed for brazing of wide range of materials: from different alloys and refractory metals to ceramics without metalization surface. Composition of STEMET is divided into groups, according to the connecting materials of the parts with their melting temperature ranges, and recommended brazing temperatures and conditions. There is demonstrated the experience of brazing of products in fields of atomic technology (brazing of spacer grids, adapters and various elements of active zones), thermonuclear technology (brazing of elements of the first wall and divertor ITER), rocket and space technology (brazing of cases for electronic devices satellites, rocket engine nozzles, elements of combustion chambers of plasma thrusters), automotive technology (brazing of automotive catalysts, ignition locks, heat exchangers and other equipment), aircraft building technology (brazing of blades and other components of gas turbine engines, heat exchangers). There are presented the results of the tests of compounds of different materials (bronze CuCrZr / tungsten, bronze CuCrZr / beryllium, titanium alloy VT1-0 (ВТ1-0) / VT1-0, zirconium alloy E110 (Э110) / E110, boron nitride ceramic / VT1-0 and aluminum alloy AV (АВ) / AV), obtained using rapidly quenched ribbon-type and heat-treated powder solders STEMET.
