Industry Applications

Our graphite materials are engineered to perform in the most demanding environments across multiple sectors.

Metallurgical Industry

Graphite and graphitized petroleum coke serve as carburizers in steelmaking. Natural graphite remains one of the primary carbon sources used globally for efficient and clean steel production.

Electronics Industry

Used in electrodes, brushes, carbon rods, mercury rectifiers, and TV tube coatings. High-grade graphite ensures reliability and conductivity in sensitive electronic components.

Flame Retardant Industry

Expandable graphite expands under heat to form insulating char layers, making it ideal for fire-retardant polymers, coatings, and construction materials.

Battery Industry

Natural and synthetic graphite are key anode materials in lithium-ion batteries. They enable reversible lithium-ion intercalation for high-capacity energy storage.

Automotive Industry

Used in friction materials for brakes and clutches. Graphite enhances wear resistance, thermal conductivity, and noise reduction in automotive systems.

Mechanical Industry

Lubricants, seals, and wear-resistant parts benefit from graphite’s self-lubricating properties and durability under high pressure and temperature.

Frequently Asked Questions

What is expandable graphite used for?

Expandable graphite is primarily used in flame-retardant applications. When exposed to heat, it expands dramatically to form a protective char layer that insulates and suppresses fire. It's widely used in construction materials, plastics, coatings, and cables.

Are your graphite products halogen-free?

Yes, our high-purity graphite and expandable graphite are specifically manufactured to be halogen-free and free of heavy metals, making them safe for sensitive industrial and environmental applications.

Can I get samples before placing an order?

Yes, we offer product samples upon request. Please visit the official website to request sample materials and detailed brochures.

What are the advantages of UHP graphite electrodes?

Ultra-High Power (UHP) graphite electrodes are made from 100% needle coke, offering low electrical resistance, high thermal shock resistance, and low consumption rates. They are ideal for electric arc furnaces in steelmaking.
