Carbon Graphite Products

Graphite electrodes
Conductive consumables for electric arc steelmaking furnaces, industrial silicon furnaces, and yellow phosphorus furnaces; these are large-diameter round rods capable of carrying high currents and withstanding high-temperature arc melting. They are essential for steel plants and represent the highest global consumption category.
Blast furnace carbon bricks and aluminum cathode carbon blocks
Large graphite/carbon blocks used for blast furnace linings and the bottoms/sidewalls of aluminum electrolytic cells; they resist erosion by molten metal and high-temperature corrosion, thereby extending the service life of the furnace.
Smelting crucibles and casting molds
Graphite crucibles for melting gold, silver, and non-ferrous metals; graphite molding dies for die-casting and metal casting—characterized by non-stick properties and resistance to cracking at high temperatures.

Hot zone components for photovoltaic monocrystalline furnaces
A complete set of internal components for monocrystalline silicon growth furnaces:
Graphite heaters, insulation cylinders, flow guides, graphite trays, crucible bases, and heating plates.
Requirements: Ultra-high purity, isotropy, low ash content, and thermal shock stability. Major suppliers of these large-sized blanks include Fangda Chengdu Carbon Materials and Henan Wanguan.
Semiconductor chip manufacturing
Wafer sintering bases, diffusion furnace chambers, graphite susceptors/trays, and ion implantation accessories.
Lithium-ion battery industry
Anode materials: Natural and artificial graphite serve as core raw materials for lithium-ion battery anodes (used in new energy vehicles and energy storage batteries).
Lithium battery sintering tooling: Graphite boats and graphite plates used for the high-temperature sintering of cathode and anode materials.

Various AC/DC motors, YZR hoisting motors, generators, wind turbine excitation motors, and core components for electric locomotives, tower cranes, and overhead traveling cranes; made of metal-graphite or electro-graphite materials, utilizing graphite for electrical conduction and commutation lubrication.
Slip rings, conductive sliding blocks, and pantograph contact strips.
Crane slip rings, mining electric locomotive components, and high-speed rail pantograph contact strips; wear-resistant and conductive, essential for high-current operating conditions.
Grounding graphite for power distribution cabinets, conductive connectors, and graphite components for lightning arresters.

Leveraging self-lubricating properties and resistance to acid/alkali corrosion:

• Mechanical seal stationary/rotating rings: Shaft-end seals for water pumps, vacuum pumps, chemical pumps, and oil pumps (silicon carbide/graphite pairings are most common);
• Graphite bearings and bushings: Oil-free bearings capable of operating in water or acidic/alkaline liquids without the need for lubricating oil;
• Graphite packing and gaskets: Corrosion-resistant sealing gaskets for pipe flanges

Graphite resists corrosion from strong acids, strong alkalis, and salt solutions—properties stainless steel cannot match:
Graphite heat exchangers, graphite reactors, sulfuric acid dilution equipment, absorption towers, and piping/fittings; widely used in fertilizer, pesticide, pickling, and fine chemical plants.

Isostatically pressed, fine-grained graphite blocks used for EDM electrodes:
For machining injection molds, die-casting molds, and precision hardware cavities; features low discharge wear and high precision, serving as a substitute for copper electrodes and suitable for large, complex molds.

Rocket nozzles and engine combustion chamber liners: High-temperature ablation-resistant carbon/carbon composite materials;
Missile thermal insulation components and graphite heat-dissipation plates for spacecraft;
Nuclear reactor core components (nuclear-grade high-purity graphite—Fangda Carbon holds production qualifications) used as moderators and reflectors.
