Product Details
OS-1: Alpha sintered Sic
Purity>98%,Relative density>96%,High Wear Resistance, High Corrosion Resistance, High Heat Resistance, Produced in the common method of Powder Metallurgy, Best performance as pure chemical compound, Most ideal for mass production on high volume.
Silicon-based ceramics are silicon carbide material containing graphite. Because of the silicon carbide matrix contains many small graphite particle dispersion, the use of matching with other materials, the friction coefficient is very small, has good self-lubricating properties, especially suitable for the production of gas seal or condition of dry friction seals use, so that the service life of seals and improve reliability.
OS-2: Reaction bonded Sic
High Thermal Conductivity, High thermal shock Resistance, Electric discharge processable conductivity.
OS-4: Sintered contain graphite silicon carbide

OS-5: Porous silicon carbide
The material to maintain a comprehensive anti-corrosion, but also add a unique spherical through improved microporous SiC excellent anti-friction properties. These independent uniform microporous scattered as fluid or lubricant storage body to help promote sliding at the interface of the surface components to maintain fluid film.
