Huahao Sealing · Carbon Graphite Components
Electrographite is carbon graphite material that has undergone high-temperature graphitization at 2500-3000°C, with crystal structure fully transformed to graphitic structure. Huahao Sealing's electrographite grades are rated 600°C with extreme chemical inertness and excellent electrical conductivity for sealing and conductive components in metallurgy, chemistry and battery applications.

| Grade Code | Temperature | Notes |
|---|---|---|
| M191T | 600°C | Carbonized, extreme chemical inertness |
Electrographite undergoes high-temperature graphitization at 2500-3000°C, with crystal structure fully graphitized (above 85%), offering much higher electrical conductivity and chemical inertness than standard carbon graphite, which is only baked at 1000-1200°C with low graphitization.
Stable at 600°C long-term in air (with anti-oxidation treatment). In inert atmosphere or vacuum, up to 2800°C. Above 600°C in air requires anti-oxidation impregnation treatment.
