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.
