What Properties of Graphite Make it Suitable for Heat Transfer?

1. High temperature resistant type: Graphite melting point is 3850, boiling point is 4,250 Shan, even if the ultra-high temperature arc burning, the loss of weight is very small, the coefficient of thermal expansion is also very small. The graphite strength increased with the increase of temperature, and the graphite strength was 1 time times when 2000 Shan.

2. Conductive, thermal conductivity: graphite conductivity than the general non-metallic ore 100 times times higher. Thermal conductivity of steel, iron, lead and other metal materials. The thermal conductivity decreases with increasing temperature, and even at very high temperatures, the graphite becomes an adiabatic body.

3. Lubrication: Graphite Lubrication performance depends on the size of the graphite scale, the larger the scale, the smaller the friction coefficient, the better the lubrication performance.

4. Chemical Stability: Graphite at room temperature has good chemical stability, acid, alkali and corrosion resistance to organic solvents.

5. Plasticity: Graphite toughness is good, can year thin flakes.

6. Resistance to thermal shock: Graphite can withstand the drastic change of temperature when it is used at ambient temperature, but the volume of the graphite material will not change when it is changed.
