Graphite has many characteristics such as high temperature resistance, thermal shock resistance, electrical conductivity, lubricity, chemical stability and plasticity, so it is widely used in many industrial fields such as new energy, metallurgy, machinery, chemistry and electrical. Graphite has both the ordinary properties of non-metallic minerals and some properties of metals and organic plastics. Therefore it is an indispensable strategic resource in the development of top military and modern industry.

Arospace industry

Battery

Natural graphite is the metamorphism of organic carbon at high temperature, is steel gray, black gray, with semi-metallic luster, crystal structure belongs to hexagonal crystal system, hexagonal layered structure, with high temperature resistance, heat conduction, electricity, lubrication, plastic and corrosion resistance.Graphite is an early anode material. Compared with other carbon materials, it has higher conductivity and crystallinity, good layered structure and charge-discharge voltage, which is also very suitable for the deactivation/embedding of cathode materials. At present, the technology is mature and the cost is low, so it is a relatively ideal anode material.

Refractory Material

having good lubricating property, trace element and low wear resistance, electric spark.

Friction Materials

Ordinary brake pads are caused by semi-metal and less metal materials. The brake pads caused by these materials have low temperature resistance, easy rust, hard substrates, easy to break the brake disc, and poor comfort. The main features of the brake pad with graphite are strong braking force, high temperature resistance, good thermal stability, small dual wear and performance, and the performance is much better than ordinary brake pads. It has been adopted by some foreign high-end cars.

Foundary coating material

Graphite powder can be used to make casting, because graphite powder has the characteristics of small coefficient of thermal expansion of iron alloy, and resistance to the change of hot and cold, can be used as a casting mold used in casting after the use of graphite powder to do black metal casting size, surface smooth yield is high, without processing or slightly processing can be used, thus saving a lot of metal;Graphite powder has good coating properties as follows: We coated the graphite powder on the solid surface, can form a solid adhesion of smooth film.Casting release agent often used in graphite powder: cryptocrystalline graphite powder (earth-like graphite powder, another name is black lead powder, microcrystalline stone toner).

Sealing Material

Expandable graphite is mainly used in sealing materials.The flexible graphite and window seal prepared by this method is a new type of high performance sealing material, which is a kind of nano-material grown in situ.Expandable graphite has good compressibility, resilience, self-viscosity, low density and other excellent properties, can be used in high temperature, high corrosion and other harsh working conditions for a long time.

Fireproof Material

Expanded graphite is mainly used in the production of flexible graphite sheets.，foam sheets, EPS sheets, coating, polyolefins,bitumen roof sheets, seal ring,back adhesives of carpets etc It has the characteristics of low sulfur content, high tensile strength, uniform body density, high surface smoothness and stable product quality. Low temperature expanded graphite has high expansion ratio and high expansion strength. Product quality is stable and so on. Mainly used in the production of various flame retardant materials.

Powder Metallurgy

Powder metallurgy graphite powder has the advantages of uniform particle, high temperature resistance, easy mixing, increase the strength of the original.Under high temperature conditions with special oxidation resistance and self-lubrication and plasticity, powder metallurgy graphite powder is used in powder metallurgy, powder metallurgy graphite powder evenly coated on the surface of the cavity, can play a good demulding role.

Lubricating Material

Graphite is a kind of crystalline form of carbon, with hexagonal lattice, atoms are arranged in layers. The distance between carbon atoms on the same layer crystal plane is 0.142 nm, and they are covalent bond with each other. The distance between layers is 0.34 nm, and the atoms are molecular bond.The interaction between layers is very small, so it is easy to slide relative between layers.Because of these structural characteristics, lead to its strength hardness is very low, plasticity is also very poor, but can play a very good anti-wear effect, is a good solid lubricant.Lubricating oil often can not be used under the conditions of high speed, high temperature and high pressure, while graphite wear-resistant materials can be used under the conditions of high speed, high temperature and high pressure.So graphite can be used as a lubricant in the machinery industry.

Pencil Lead

Graphite is a solid, scaly, metallic substance made of carbon. It is so stable that there is nothing in the body that can destroy it, so pencil leads are not toxic.Its soft texture is one of the softest ores, and its uses include making pencil leads and lubricants.Just run it across the paper and leave a mark.If viewed under a magnifying glass, pencil marks are made up of very fine graphite grains
