Hebei Fengchao Import and Export Co., Ltd. is one of the most reliable manufacturers and suppliers of natural flake graphite in China. With a professional production team, we are able to meet the needs of the majority of our customers. If you're going to wholesale bulk natural flake graphite made in China, welcome to get pricelist from our factory.
Our natural flake graphite retains intact flake crystal morphology after mineral processing and purification, featuring stable fixed carbon content and low proportion of harmful impurities. Its unique lamellar crystal structure endows the product with excellent self-lubricating property, good thermal shock resistance and high-efficiency release effect. Multiple mesh sizes are available, suitable for refractory coatings, friction material formulations, lubricating additives and casting release agents.
Natural flake graphite is crystalline mineral graphite obtained by flotation, graded by flake size with high fixed carbon grade and low volatile content. The lamellar crystal structure enables good sliding property of the powder, and it shows favorable chemical inertness against most molten slags. Products of different flake sizes have distinct performance: large flakes enhance high-temperature resistance while fine powder is suitable for composite filling. Widely applied in brake friction formulations, expandable graphite production, magnesia-carbon refractory bricks, conductive coatings and fillers for polymer composite materials.
Our intact flake graphite is produced from high-grade graphite ore through multi-stage flotation purification. With professional mineral processing equipment and refined grading control, the product has stable fixed carbon and uniform mesh size, matching various industrial formulations.

FAQ
Q: What factors affect the flake retention rate of natural flake graphite?
A: The preservation of large flakes mainly depends on grinding intensity in mineral processing. We adopt low-intensity gentle grinding technology to minimize mechanical crushing and protect large crystal flakes.
Q: What fixed carbon ranges are available for natural flake graphite?
A: Conventional flotation grades have fixed carbon of 80% 96%. Higher carbon content requires further chemical purification. Please specify the target carbon content during inquiry.
Q: Does flake graphite tend to agglomerate during storage? How should it be stored?
A: The powder absorbs moisture in high-humidity environments and may form slight agglomerates. It is recommended to keep the packaging sealed and store in a cool, dry and ventilated warehouse.
Q: Can the particle size distribution of powder be adjusted according to customers' formulations?
A: Yes. Custom particle size ranges can be achieved by air classification and screening. Customers may provide sieve analysis indicators corresponding to their formulations.
Q: What is the typical moisture content of flake graphite upon delivery?
A: Conventional delivery moisture ≤0.5%. If strict low moisture requirements are required for projects, an enhanced drying process can be added.
Q: What key technical information should be provided for inquiry?
A: Please state the target fixed carbon grade, mesh size or particle size distribution, maximum allowable moisture, and downstream application industry (refractory, friction materials, coatings, etc.).
