What are the advantages of graphite electrodes?
(1) The increasing complexity of mold geometry and the diversification of product applications have led to higher and higher requirements for discharge accuracy of spark machines. The advantages of graphite electrodes are easier processing, high removal rate of electrical discharge machining, and low graphite loss. Therefore, some group-based spark machine customers abandon copper electrodes and switch to graphite electrodes. In addition, some special-shaped electrodes cannot be made of copper, but graphite is easier to form, and copper electrodes are heavy and not suitable for processing large electrodes. These factors have caused some group-based spark machine customers to use graphite electrodes.

What is a graphite electrode?
Graphite electrode refers to a kind of resistant material made by using petroleum coke and pitch coke as aggregate and coal tar pitch as binding agent through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. High-temperature graphite conductive material, called artificial graphite electrode (referred to as graphite electrode), to distinguish it from natural graphite electrodes prepared from natural graphite.

Physical properties and application fields of amorphous graphite
Amorphous graphite, earthy graphite, is also microcrystalline graphite and black lead powder. Amorphous graphite does not really have no graphite crystals like his name, but its crystals are too small and have a microcrystalline structure. X-ray analysis shows that amorphous earthy graphite contains 15% to 45% of crystalline graphite, so amorphous graphite is also called microcrystalline graphite.

Types and uses of natural graphite
The process performance and use of graphite are mainly determined by its degree of crystallinity. Natural graphite can be divided into crystalline graphite (flake graphite) and cryptocrystalline graphite (earth graphite) according to its crystal form.
