Natural Flake Graphite

Natural Flake Graphite

Flake graphite is a natural solid lubricant with a layered structure. It has complete crystallization, thin flakes, good toughness, and excellent physical and chemical properties such as good temperature resistance, self-lubrication, conductivity, thermal shock resistance, and corrosion resistance.

Product Category

Industry Application

Spherical Graphite

Spherical Graphite

Spherical graphite is made from high-quality and high-carbon natural flake graphite. First, the graphite dry concentrate undergoes processes such as coarse crushing, shaping, and magnetic separation in the spherical graphite workshop to form the initial product. It then enters the purification works...

High Purity Graphite

High Purity Graphite

High-purity graphite is purified by removing impurities and acids from flake graphite, with a carbon content of 99.99% min. It is resistant to high temperatures, corrosion, and oxidation.

Product Category

Industry Application

Colloidal Graphite

Colloidal Graphite

It has excellent high lubrication, high conductivity, high adsorption, and catalytic performance, with extremely high plasticity.

Product Category

Industry Application

Expandable Graphite

Expandable Graphite

Expandable graphite is a loose, porous, worm-like substance obtained by intercalating, washing, drying, and high-temperature expansion of natural flake graphite.

Product Category

Industry Application

Graphite Carburizer

Graphite Carburizer

Carburizer are divided into common carbon enhancers and graphite carbon enhancers. Depending on the different smelting processes, they can add carbon during steelmaking and casting to increase the strength of steel and castings. Graphite Carburizer can be divided into the following four types: graph...

Industry Application

Granular Graphite( Artificial)

Granular Graphite( Artificial)

Granular Graphite has a smooth feel. Graphite is characterized by its low density, high-temperature resistance, self-lubricating properties, high electrical and thermal conductivity, strong wear resistance, high stability, thermal shock resistance, and good plasticity.

Product Category

Industry Application

Graphite Emulsion

Graphite Emulsion

The main component of graphite emulsion (graphite slurry) is graphite (micro-powdered graphite). Due to its milky state, it has excellent lubricating properties, release properties, chemical stability, high-temperature adhesion, and improves mold life and forging quality."

APPLICATION FIELDS

Refractory

Graphite products can also be made by using carbon-based refractory materials in an electric resistance furnace, where they are heated to 2500–2800°C to achieve graphitization.

Casting Materials

Casting graphite powder is widely used in casting, coating, batteries, carbon products, pencils, pigments, refractory materials, smelting, and as a carbon additive.

Friction Materials

Friction materials are components used in power machinery that rely on friction to perform braking and transmission functions.

Lubrication Materials

Graphite, as a solid lubricant, can be used in its dry powder form for splash lubrication or made into water-based and oil-based additives.

Powder Metallurgy

In aerospace, important powder metallurgy materials include brake pad materials, porous materials, and high-strength powder alloys.

Carbon Brushes

Carbon brushes have excellent lubrication properties, low trace elements, wear resistance, and minimal electrical sparking.

Batteries

Graphite is primarily used in low-mercury and mercury-free alkaline battery cathode materials to improve current, voltage, and extend discharge time.

Chemical Industry

Due to its many excellent properties, graphite is widely used in various industrial sectors including metallurgy, machinery, electrical, chemical, textile, and defense.
