Grade characteristics
Why are SiAlON ceramics so effective at high-speed machining of heat-resistant alloys?
Silicon nitride (Si3N4) is combined with Aluminum (Al) and oxygen (O) to make SiAlON.
Sialon has needle-shaped particles similar to that of Silicon nitride.
The arrangement of these particles makes the material withstand the impact force during cutting.
The addition of the alumina improves its heat-resistance characteristics.
The property advantages makes it perfect for machining heat-resistant alloys.
