Product Description

Si3N4 Silicon Nitride Guide Roller for the Foundry Industry:

Silicon nitride guide rollers are more resistant to high temperature, high hardness, high toughness, impact resistance and oxidation resistance. At the same time, silicon nitride guide rolls are oil-free, self-lubricating, low in density and light in weight. The service life is more than ten times that of the alloy guide roller.

 

Silicon Nitride (Si3N4) Characteristics:
1. Good thermal shock resistance
2. Creep resistance
3. Low density
4. High fracture toughness
5. High hardness and wear resistance
6. Electrical resistivity
