The crystal structure delivers excellent lubricity, thermal conduction, and heat resistance. This guarantees integral, reliable, and consistent performance.
In modern manufacturing, demand continues to rise for high-purity, structurally consistent carbon materials. Whether employed in metallurgy, advanced energy storage systems, high-temperature refractories, or specialized friction materials, our natural graphite powder provides consistent, reliable performance under the most demanding industrial conditions. Our state-of-the-art purification and milling technologies ensure precise particle size distribution, optimal carbon purity, and minimal moisture levels, providing global manufacturers a distinct competitive advantage in product quality, operational efficiency, and cost-effectiveness.
Key Physical & Chemical Advantages
Superior Electrical & Thermal Conductivity: Exceptional conductivity coefficients make it the ideal choice for advanced energy applications, conductive coatings, electrical brushes, and specialized thermal management solutions.
Exceptional Thermal Resistance & Stability: An extremely high melting point and resilience against intense thermal shock enable it to endure extreme operational temperatures without structural degradation.
Natural Self-Lubricating Properties: A low coefficient of friction, derived from its unique layered crystal structure, makes it ideal for high-performance lubricants, industrial greases, and powder metallurgy components.
Chemical Inertness & Corrosion Resistance: High resistance to acids, alkalis, and aggressive chemical environments ensures long-term operational durability and reliability in harsh chemical processing conditions.
High Crystallinity & Structural Integrity: The well-ordered carbon atom lattice provides exceptional structural strength, oxidation resistance, and dependable batch-to-batch consistency.
Grade Classifications & Technical Parameters
To accommodate diverse industrial specifications, we offer customized graphite grades precisely categorized by fixed carbon purity, mesh particle size, and expansion characteristics:
1. Standard Flake Graphite Series
Our standard flake series is segmented into High Purity Graphite (≥99.9% fixed carbon, ≤0.3% moisture), High Carbon Graphite (≥94%–99.5% fixed carbon, ≤0.5% moisture), and Medium Carbon Graphite (≥80%–93% fixed carbon, ≤1% moisture). All products maintain a high granularity index exceeding 80.0% across a wide mesh distribution, from coarse 32 mesh to ultra-fine 325 mesh.
2. Expandable Graphite Series
Specifically engineered for intumescent flame retardants, high-temperature sealing, and gasket manufacturing, this series offers high expansion rates ranging from 100 ml/g up to 400 ml/g across mesh sizes from 32 mesh to 150 mesh. These grades feature fixed carbon contents between 85.00% and 99.50% with rapid activation starting at temperatures ≥950°C.
Primary Industrial Applications
Leveraging its versatile physicochemical profile, our natural graphite powder serves as an indispensable raw material across numerous global sectors:
