Solid Graphite Rod

Solid Graphite Rod is precision-machined from high-grade industrial graphite materials, providing reliable heat resistance, stable dimensions, and reduced maintenance needs for demanding thermal processing applications.  

Features a uniform fine-grain graphite structure with controlled porosity, significantly improving resistance to chemical attack from molten metals and reactive industrial gases.

High carbon purity with ash content controlled at ≤0.05% to effectively minimize contamination risks in sensitive thermal processing and semiconductor applications.

Premium grades with carbon content up to 99.99% are available for specialized cleanroom and advanced tech applications requiring strict material purity control.

Standard production holds precision tolerances within ±0.05 mm, with advanced high-precision capabilities down to ±0.01 mm, supporting seamless installation in vacuum furnaces and complex industrial equipment.

A stable bulk density of 1.75–1.85 g/cm³ ensures structural integrity and dimensional stability during long-term, high-temperature operations.

Diameter Range: Available from 10 mm up to 500 mm(Custom diameters available upon request).

Length Range: Standard lengths up to 2000 mm; precision cutting to specific sizes is fully supported.

Advanced Machining & Treatments: We offer custom CNC turning, drilling, threading, and optional anti-oxidation coatings or impregnations to extend service life in open or semi-sealed environments.

Vacuum Furnaces: Widely utilized as heating elements, support columns, electrical heating electrodes, and structural components compatible with leading furnace brands (e.g., Ipsen, Leybold, TAV).

Non-Ferrous Metallurgy: Applied as degassing rotors, fluxing tubes, and stirring rods for high-efficiency processing of molten aluminum, zinc, and copper.

Semiconductor & Photovoltaic: High-purity ultra-clean grades utilized in crystal pulling furnaces, silicon ingot growth, and critical thermal field components.

Chemical Engineering: Deployed for highly corrosion-resistant components, mechanical seals, and chemical heating elements operating in aggressive fluid environments.

Raw Material Selection: Strict screening and lab testing of premium petroleum coke and specialized coal tar pitch.

Mixing & Kneading: Precise automated proportioning and thermal kneading to guarantee a uniform, isotropic material composition.

Molding / Extrusion: Advanced isostatic pressing or high-pressure extrusion molding to achieve optimized target density and strength.

Baking & Graphitization: Extended high-temperature graphitization treatment exceeding 2500℃ to completely transform carbon structures into crystalline synthetic graphite.

Precision CNC Machining: Utilizing multi-axis CNC machining centers to meet ultra-tight tolerances (regular ±0.05 mm, high precision ±0.01 mm).

Production Capacity: Fully automated molding lines and large-scale, high-temperature graphitization furnaces ensure stable, uninterrupted volume supply for global wholesale and industrial clients.

Strict Quality Control: Every single production batch undergoes rigorous density, purity, and mechanical strength testing in strict compliance with ISO 9001 quality management standards. Independent third-party inspections (such as SGS or BV) are fully supported prior to dispatch.

Complete Traceability: A comprehensive Material Testing Report (MTR) featuring actual physical property batch data is provided with every single shipment.

Packaging Standard: Multi-layer protective packaging featuring internal moisture-proof plastic film, thick shock-absorbing foam padding, and external export-standard, fumigation-free heavy-duty wooden crates to prevent transit damage.

Global Shipping Partners: Long-term strategic cooperation with reliable international freight forwarders supporting flexible trade terms including FOB, CIF, DDP, and EXW to all major ports worldwide.
