Graphite Rod
We also can supply big diameter graphite rod, for process graphite crucible or other graphite parts.
Graphite Rod Specifications Range:
Process engineering characteristic of graphite rod
1. High temperature resistance: Graphite Rod is one of the currently known highest-temperature resistance materials. Its melting point is 3850 ° C ± 50 ° C, boiling point up to 4250 ° C.Under 7000 ° C ultra-high temperature electric arc, the loss of graphite is the minimum, only 0.8% of the total weight in 10 seconds, Thus, the high temperature resistance of graphite is very prominent.
2. Specific thermal shock resistance: Graphite has good thermal shock resistance, when the temperature changes suddenly, the crack will not emerge due to the small thermal expansion coefficient
- Thermal and electric conductivity: Graphite has good thermal conductivity and electrical conductivity. Compared with the general material, its thermal and electrical conductivity is very high. Four times higher than stainless steel, two times higher than carbon steel and 100 times higher than the average non-metallic.
- Lubricant: The lubricating properties of the graphite is similar to MoS2, the friction coefficient is less than 0.1. Its lubricating properties changes from the size of the graphite flake, the bigger the flake is, the smaller the coefficient is, and the lubricant property will be better.
- Chemical stability: Graphite has good chemical stability at room temperature. Resistance to acid, alkali, and organic solvents.Our Graphite Rod diameter is 2-280mm, length is 30-2000mm, mainly used in metallurgychemical industryelectrical industry and mechanical industry.
