High Grade Graphite Round Rod Chemical Composition: Carbon

Backed by years of industry experience, we are engaged in supplying High Grade Graphite Round Rod in Pingdingshan, Henan, China. Details as given below:-


(1) High temperature resistance, graphite melting point is 3850 + - 50 a , boiling point is 4250 a , even by the ultra high temperature arc ignition, weight loss is small, thermal expansion coefficient is small; Graphite with temperature increase and strengthen the intensity, at 200 a , graphite double strength;

(2) Good conductivity, thermal conductivity, the conductivity of graphite non-metallic one hundred times higher than the average, thermal conductivity than steel, iron, lead and other metal materials, the coefficient of thermal conductivity decreases with temperature rise, and even at high temperatures, as insulators; The lower the coefficient,

The lubrication performance of graphite depends on the size of graphite scale. The larger the scale, the better the friction and lubrication performance of graphite.

In addition, graphite has good chemical stability at room temperature, and can resist acid, alkali and corrosion of organic solvents.

Type-plasticity. Graphite has good toughness and can be ground into thin sheets.

2) Thermal shock resistance. Graphite can withstand severe changes in temperature without damage when used at room temperature. When temperature changes, the volume of graphite changes little and no fission occurs.
