Dongxin UK


Silicon carbide engineered ceramics have many excellent functions. Silicon Carbide products have the advantages of high temperature resistance, high hardness, wear and corrosion resistance.

Dongxin can offer 5 grades of Silicon Carbide for use in a variety of applications, being widely used in sealing, machinery, metallurgical, petroleum, chemical, automotive and aerospace applications throughout the world.

Reaction Bonded Silicon Carbide (RSIC) has high wear, temperature and corrosion resistance, making it ideal for use in applications such as mechanical seal ring or nozzle.
Sintered Silicon Carbide (SSIC) possesses higher wear, corrosion and temperature resistance over RSIC, making it ideal to use for sealing ring and with a higher hardness and strength it can be used in further applications such as armour plating.
Graphite particles distributed throughout the material give higher friction resistance which allows the material to have enhanced wear resistance. This gives allows the material dry friction properties in applications of limited or unstable lubrication, while still possessing the corrosion and temperature resistance properties of DX201.
Micropores on the surface of the material act as fluid storage chambers, allowing the material to reduce the surface friction and heat. When the lubricating media is not sufficient, the liquid stored in the micropore will help to promote lubrication, allowing dry running capability in applications where the lubricating media is limited or not
Containing both fine graphite particles and spherical pores, the DX204 material has enhanced performance by bringing together all of the properties of DX201, DX202 and DX203.
