Below is a list of SiC Heating Elements manufacturers from Concord, North Carolina. A SiC heating element, or silicon-carbide heating element, is a type of non-metallic high temperature ceramic heating element. Using silicon and carbon as the main raw materials, SiC heating elements are capable of higher operating temperatures and watt loadings than metallic heating elements. Typically either an extruded tubular rod or cylinder, SiC heating elements are self-supporting and can be used in furnaces that are too wide or too long for metallic or MoSi2 heating elements.
