Overview
Silicon Nitride Ceramic Mechanical Seal and Shaft Sleeve Fine Ceramic Rings
Reputation depends on quality, quality comes from hard!
Product Description
Silicon Nitride Ceramic :
Silicon nitride exceeds other ceramic materials in thermal shock resistance. It also offers an excellent combination of low density, high strength, low thermal expansion and good corrosion resistance and fracture toughness.
silicon nitride has been used in a number of industrial applications, such as engine components, bearings and cutting tools.
Key Properties
* High strength over a wide temperature range
* High fracture toughness
* High hardness
* Outstanding wear resistance, both impingement and frictional modes
* Good thermal shock resistance
* Good chemical resistance
Typical Uses
* Rotating bearing balls and rollers
* Cutting tools
* Engine moving parts — valves, turbocharger rotors
* Engine wear parts — cam followers, tappet shims
* Turbine blades, vanes, buckets
* Metal tube forming rolls and dies
* Precision shafts and axles in high wear environments
* Weld positioners
Properties
High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1200°), good thermal diffusivity, good insulativity, low cost etc.
