The graphite heating plate is the electric heating body parts made of graphite materials. Graphite has good electrical and thermal conductivity, and it is commonly used in special industrial furnaces as a heating element. 

The graphite heating plate element has good high-temperature strength, and as the temperature increases, the strength gradually increases and it will exceed all oxides and metals. the graphite has some properties of metals and ceramics, with good electrical and thermal conductivity, and a small thermal expansion coefficient, so the graphite is one of the best thermal shock resistance of materials.

 * Low wettability to molten metals 
 * Fine-grain
 * High density
 * Homogeneous structure
 * High mechanical strength
 * Excellent thermal conductivity
