Tungsten carbide is a chemical compound of carbon and tungsten (semiarid and monocarbide tungsten). In hardness it is comparable with diamond and has a high wear resistance, oxidation resistance and extremely high melting point.
The scope of
Tungsten carbide is widely used in the production of instruments of exceptional hardness and corrosion resistance. It is also used for wear-resistant hardfacing on parts that operate in conditions of intensive abrasive wear in the manufacture of drills, wheels, cutters and electrodes. Autogenous welding electrode brands WSC and SFTC G21-GF-55-CG (DIN 8555), filled with melted crushed and spherical tungsten carbide, used for surfacing low-alloy and non-alloy steel, the cutting edges of tools. For electric welding hard alloy low-alloy and non-alloy steel, uses a special electrode filled with spherical tungsten carbide, brand WSC E21 UM-GF-60-CG. Such electrodes, as E21-UM-60-CGZ sintered and compacted is used for surfacing parts subject to great wear by friction. Autogenous flexible welding electrode with melted, crushed tungsten carbide G21-UM-55-CG is used for surfacing astenicheskiy and ferrite rods, cast iron, deep drilling equipment, augers conveyors, etc.
Varieties of carbide-tungsten electrodes
— spherical molten flexible electrodes SFTC G21-UM-55-CG, filled with spherical molten tungsten carbide;
— filled with molten crushed tungsten carbide and NiCrBSi, brand WSC G21-GF-55-CG;
— filled with molten spherical tungsten carbide and NiCrBSi, brand SFTC G21-GF-55-CG.
Non-consumable tungsten electrodes produced in accordance with GOST 23 949−80. Manufacture of carbide-tungsten electrodes normalizes GOST 21 448−75. Such electrodes are of circular cross-section (Ø0,5 3×40 mm) and flat (1,5x3x40, 1,5x2x40, 4x2x40). Technology of production of carbide-tungsten electrodes and characteristics of the composition provide high thermal stability and excellent operational stability.
All of the party carbide-tungsten electrodes are certified. In the specifications reflected data on the percentage composition and mechanical properties of products. We can easily buy in bulk any semi-finished products for large-scale production. We also work with retail buyers. A high level of service and speed of service are the face of our company.
