Silicon Carbide (SiC) has exceptional properties, including high hardness, high thermal conductivity, high chemical and thermal stability, wide bandgap, excellent electrical properties, lightweight, and biocompatibility. These qualities make SiC a highly sought-after material in various industries, including abrasives, refractory materials, electronics, automotive and aerospace, coatings, and medical implants.

1) Sintered Silicon Carbide with Graphite (VSG1)
VSG1 is graphite blended with graphite, and has improved tribological properties compared to VSS1 to further improve running efficiency. This is useful to increase seal life in applications with volatile and low boiling point fluids that poorly lubricate the seal faces. This material has a black flecked appearance.
Features & Benefits
- Pure with no additive
- Rougher surface finish and fine-grain
- Higher strength
- Superb chemical resistance
Suitable Applications
Used in tribological systems with heavy loads.
