Roughing (no scale) to semi-finishing heat resistant alloys ｜ Sialon ceramic
Roughing with no scale to semi-finishing heat resistant alloys
Turning/Grooving/ Milling
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.
