We machine parts from a full range of graphite materials — selecting the grade, structure and impregnation to match your temperature, media, strength and purity requirements.
Different forming methods and structures suit different parts.
Isostatically pressed for a fine, uniform, isotropic structure — ideal for EDM, continuous casting and semiconductor tooling.
Extruded grades for electrodes and large rods and tubes; good electrical conductivity.
Pressed and vibration-molded blocks for large structural and furnace parts.
Small grain size for high strength, tight tolerances and detailed machined parts.
Purified to very low ash for semiconductor and precious-metal melting.
Carbon-graphite with impregnation for seals, bearings, vanes and sliding parts.
Indicative ranges across our graphite grades.
| Property | Typical Range |
|---|---|
| Bulk density | 1.70 – 1.90 g/cm³ |
| Grain size | Fine to ultra-fine |
| Flexural strength | 25 – 60 MPa |
| Compressive strength | 50 – 120 MPa |
| Specific resistivity | 8 – 15 µΩ·m |
| Shore hardness | 40 – 75 |
| Ash content | ≤ 0.1% (high-purity to ppm) |
| Max service temp. | up to 3000°C (vacuum / inert) |
| Thermal expansion | Low (CTE) |
Indicative only: values vary by grade and part. We confirm the exact specification — density, strength, resistivity, ash and purity — against your selected material.
Surface and structure treatments tailored to the application.
Seals porosity and improves strength and leak-tightness.
Antimony / babbitt impregnation for higher load and wear.
Chemical resistance and low friction for sealing parts.
Surface treatment to slow oxidation at high temperature.
High-temperature / halogen purification to low ash (ppm).
Machined to drawing with tight tolerances.
Feedstock and carbon materials we also supply.
Calcined petroleum coke as carbon source and recarburizer.
Low-impurity needle coke for graphite-electrode production.
Binder used in electrode and carbon-product manufacturing.
Natural flake graphite for crucibles, packing and emulsion.
