Ceramic Parts and components manufacturer,OEM
High Quality, High Precision, Delivery on time, Factory Price
Precision ceramic insert with ceramic high strength, high hardness, wear resistance, high temperature resistance, oxidation resistance and chemical stability and other characteristics, is a very important tool and structural materials, it has a small density, high hardness, wear resistance and good thermal conductivity, not because of sudden heat and brittle.
Ceramic material composition:
· 95%--99.99% Alumina (Al2O3) · Silicon Carbide · Silicon Nitride
· TTZ: Magnesia partially stabilized Zirconia (ZrO2) · YTZP: Yttria partially stabilized Zirconia (ZrO2)
· ZDY: Yttria fully stabilized Zirconia (ZrO2)
The property of the ceramic:
·Excellent physical & chemical stability ·High temperature resistance(up to1750℃)
·Excellent wear & pressure & corrosion& insulation resistance and thermal conductivity..
