Sintered Silicon Carbide (SSiC)

The material does not contain free silicon and small grain, more than RBSiC more high temperature, high strength, high hardness, strong corrosion resistance, anti-oxidation and other excellent performance, is the developed countries manufacturing machinery seal ring, blasting nozzle, Magnetic pump, shielding pump components preferred general materials, especially for the transmission of strong acid, alkali and other corrosive media in the use of the conditions.

  • Higher Hardness (92.3 Rockwell)
  • Higher Strength (401 MPa)
  • Anti-Oxidation Performance
  • Higher Temperature Resistance
  • Higher Corrosion Resistance
  • Density 3.12 g/cm³

Sintered Silicon Carbide with Graphite (SSiC+C)

The material is evenly distributed and independent of the non-connected spherical microporous, can be used as a fluid medium storage chamber to make the media can fully play the effect of lubrication. This microporous lubrication mechanism makes microporous SSiC better than conventional reactive sintering and pressureless sintered silicon carbide under many operating conditions. Used in limited lubrication conditions and hard to hard grinding combination of harsh application environment, suitable for the production of pump seals, sliding bearings.

  • Fine graphite particlesEnhanced performance from SSiC
  • Improved self-lubrication
  • Improved dry friction resistance.
  • Typical Application Conditions:
  • High corrosion
  • High load
  • Dry friction

Porous Sintered Silicon Carbide (Porous SSiC)

The material is based on the SSiC added fine graphite particles made by high temperature sintering. This material not only has the excellent performance of SSiC, but also because of the presence of graphite particles to improve the self-lubricating properties and anti-dry friction, suitable for strong corrosion, high load, dry friction, hard-hard team conditions Use, such as sliding bushings and so on.

  • Spherical pores formed during sintering process
  • Typical Application Conditions:
  • Hard conditions of limited lubrication
  • Hard-face to hard-face friction

Porous Silicon Carbide with Graphite (Porous SSiC+C)

Carbon-Graphite is made of graphite that is dipping by different resins or metal materials. It has the features of good corrosion resistance, self-lubrication, high thermal conductivity, low expansion coefficient, low friction coefficient and so on, widely used in the fields of mechanical seals, sliding bearing and radial split seal.
