Properties

Thermal conductivity in international units (W/m.K)

With thermal conductivity of 130 W/m.K, silicon carbide outperforms most of the materials used for the construction of corrosion-resistant process equipment.

 

Thermal conductivity in imperial units (BTU.inch/hr.ft2.°F)

With thermal conductivity of 900 BTU.inch/hr.ft2.°F, silicon carbide outperforms most of the materials used for the construction of corrosion-resistant process equipment.

CORRESIC® Silicon carbide

GAB Neumann’s CORRESIC® product portfolio includes silicon carbide plates, block and tube, and shell and tube heat exchangers. Our individual plates, blocks, and tubes are all made of pressureless sintered silicon carbide. This manufacturing process confers its almost universal corrosion resistance to silicon carbide, its outstanding thermal conductivity, it hardness, and its mechanical strength.
