Flake graphite granules

The hexagonal crystal system contains natural crystalline graphite. This graphite has the appearance of fish phosphorus. The material is highly resistant to heat, electric conductivity and thermal conductivity. It also has excellent lubrication, plasticity as well as acid and alkali resistance.

Natural Flake Graphite properties:

Flake graphite exhibits complete crystallization and thin flakes. It also has excellent chemical and physical properties. The material has high thermal conductivity as well as electrical conductivity.

Graphite powder exhibits good electrical conductivity. Although it is not comparable with iron, copper, aluminum and other metals in terms of electrical conductivity, graphite powder has an excellent one. It is three to five times as high as carbon steel and five to five times as high at stainless steel. And it’s 100 times better than any other non-metallic materials.

Flake graphite powder can be lubricated well. The friction coefficient for graphite powder is less than 0.01. However, the level of lubrication depends on how large the flake. The friction correlation coefficient of graphite powder is smaller and therefore the performance of the lubricating agent will be better for larger flakes.

Flake graphite from natural sources is very resistant to heat shock. It is resistant to temperature shocks and has a low thermal expansion coefficient.

Natural Flake Graphite Apps:


Flake graphite is used extensively in advanced refractories, coatings and metallurgical industries. A lot of work is required to make graphite oil, which can be used for lubricants as well as mold release agents and wire drawing agents.


Flake graphite, a functional additive to coatings is used primarily for fire-resistant and anti-corrosion coatings.

This anti-corrosion material is made from carbon black, oil and talcum powder. It has excellent corrosion resistance to solvents and chemicals. Chemical pigments, such as zinc yellow, can be added to improve the antirust effect.

Expandable graphite, which can also be called a fireproof material, is made by electrochemical or chemical treatment of natural graphite flake raw materials.

Flake graphite is a carbon-based, conductive filler that can also be used for coatings.
