jinyu silca sic heating element is a type of non-metal high temperature heating device. these sic productsare made from fine quality green silicon carbide as its main raw material. the raw material is made first in to a blank, followed by high temperature silication and recrystallization, and becomes high quality stick shaped sic electric heating devices. compared with metal electric heating material, this type of non-metal elements is featured of high operation temperature, anti-oxidization, long service life, little deformation, easy installation and maintenance. because of these advantages, sic electric heating elements is widely used in various industries that require high temperature electric furnaces and heating devices. these typicalapplications include electronics, magnetic materials, powder metallurgy, ceramics, glass,metallurgy and machinery. products specification: rod type, u type, w type (three phase type), solid rod type, spiral type, 5 piece type (dual hot zone). sizes are available from dia 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, 30mm, 31.7mm (1.25inch), 35mm, 38.1mm (1.5 inch), 40mm, 44.4mm (1.75 inch) to 54mm (2.125 inch) for all types.
