Abroad spectrum of amorphous solders with the STEMET trademark has been developed in the form of a thin pliable ribbon for soldering articles made of copper, aluminum, titanium, alloys based on them, stainless steels, heat-resistant nickel alloys, zirconium, refractory metals and their alloys, metal-ceramic materials, graphite, ceramics, and other materials.

The heightened diffusion and adhesion activity of amorphous alloys on melting makes them suitable for the soldering and diffusion welding of the most diverse materials.

Because of their brittleness in the crystalline state, many alloy solders cannot be obtained in the form of a thin foil by conventional methods and are, therefore, used only in the form of powders. Amorphous foils of such alloys are strong, flexible, and ductile. The thin foil of solder is highly convenient for soldering flat surfaces of various shapes and can, moreover, be stamped into blanks to ensure exact dimensions of the joint. Amorphous foil can conveniently be inserted directly into assembly clearances of optimal size in strictly required amounts, which makes for joints of maximum strength.

The highly homogeneous chemical composition of the multicomponent alloys and the structure (absence of a long-range order in the arrangement of the atoms) of amorphous solders assures narrow soldering intervals and makes it possible to achieve homogeneous joints without microscopic segregations or gas inclusions. This guarantees strong soldered joints.

Amorphous solders are also superior to powdered solders because they are highly efficient, environmentally clean, assure economical and convenient processes of assembly and soldering, a good quality of the soldered joint, reduce soldering costs, guarantee the spread and homogeneity of the solder, its minimal losses, a minimal thickness of the joint, and quick production of the soldering materials in accordance with the geometric shape and dimensions of the soldering site.

In manufacturing such items as vacuum current carriers, the use of STEMET amorphous solders in soldering metals with ceramics slashes labor intensity to a fraction.

In soldering current-carrying parts of the collector segments of d.c. machines, the use of the STEMET amorphous solder has considerably reduced the electric resistance of the soldered joints, cut the consumption of solder to one-fifth, and completely dispensed with the use of silver-containing solders.
