Material grades

Glassy carbon is available in the two grades SIGRADUR® K and SIGRADUR® G. The both material grades have different manufacturing temperatures. Therefore they differ in their physical and chemical properties. SIGRADUR® G has a higher electrical conductivity, a higher corrosion resistance to oxidizing substances and a high temperature resistance up to 3000C. SIGRADUR® K has a higher hardness and density.
