Graphite is one of the highest temperature-resistant materials known today. The melting point is 3850℃±50℃, and the boiling point is 4250℃. Under 7000℃ ultra-high temperature arc for 10S, the loss of graphite is relatively small, and the weight loss of graphite is 0.8%. It can be seen that the high-temperature resistance of graphite is very prominent.
Graphite rods are hexagonal crystalline carbon with a metallic luster. According to its source, it can be divided into natural and artificial graphite rods.
Graphite rod flake is a natural solid lubricant with a layered structure, which is abundant in reserves and low in price. Graphite rod scales have complete crystallization, t, hin scales and good toughness, excellent physical and chemical properties, good electrical conductivity, electrical conductivity, thermal shock resistance, corrosion resistance, etc. Flake graphite rods are high-carbon high carbon graph medium-carbenium carbon gra, pillow-carbon low carbon graphite rods according to the level of carbon content.
The life of graphite rods has a great relationship with their oxidation degree. At room temperature, graphite rods start to oxidize from above 500 degrees Celsius, but the degree of oxidation is very small. With the change of time and the decrease in temperature, the degree of oxidation of graphite rods began to intensify. Impregnated graphite rods have better high-temperature resistance than ordinary graphTon order to effectively prolong the service life of graphite rods, nitrogen or ammonia can be added for anaerobic protection, or some anti-oxidation coatings can be applied to the graphite rods themselves.
Graphite is the name of a mineral usually found in metamorphic rocks, formed by regional metamorphism or magmatic intrusion of coal or carbonaceous rocks (or sediments).
Graphite is an allotrope of carbon. Each carbon atom is surrounded by three other carbon atoms in a honeycomb hexagonal arrangement with weak van der Waals attraction between the layers. Graphite is an electrical conductor because each carbon atom emits an electron, which is free to move. Graphite is one of the soft minerals, opaque, greasy to the touch, ranging in color from iron black to steel gray, in crystals, flakes, scales, stir, ps, layers, or scattered in metamorphic rocks.

Heating graphite rod high-purity graphite material specifications are complete. The life of a graphite rod has a lot to do with its degree of oxidation. At room temperature, graphite rods start to oxidize from above 500 degrees Celsius, but the degree of oxidation is very small. With the change of time and the increase in temperature, the degree of oxidation of graphite rods began to intensify. Impregnated graphite rods have better high-temperature resistance than ordinary graphite rods. To effectively prolong the service life of the graphite rod, nitrogen or ammonia can be added for anaerobic protection, or the graphite rod itself
Good thermal and electrical conductivity Compared with copper, graphite electrodes have the advantages of less consumption, fast discharge speed, lightweight, and small thermal expansion coefficient. Hence, they gradually replace copper electrodes and become the mainstream of EDM electrodes. In contrast, graphite electrode materials have the following advantages: 1. Fast speed: graphite discharges 2-3 times faster than copper, and the material is not easily deformed. It has obvious advantages in the processing of thin rib electrodes. The softening point of copper is about 1000 degrees. It is easy to deform when heated, and the sublimation temperature of graphite is 36
