Electric heaters of SIC are widely used in various high-temperature electric furnaces and kilns and other electricheating devices for the manufacturing of ceramics, in powder metallurgy and mechanical engineering. Most often the devices go wrong due to compound between the parts. Typically, the current leads are made from aluminium strips, and the connection with the electric heater is carriedout by means of clamps or other mechanical clutches. It is often found at the junction of cracks, and the compounds itself have high electrical resistivity. The paper discusses the basic properties of the SiC heaters, proposes and investigates a new method for obtaining permanent fixing current supply via annular metal elements crimped using the pulsed magnetic material processing (MPP)
