Ceramic Gear Higher Hardness Machinery Alumina Zirconia Precision Gear
A gear is a mechanical element on the rim of which a gear is continuously engaged to transmit motion and power.
As a the manufacturer of ceramic gears, us offer a wide the type or sizes of the ceramic gears for industry machinable and ceramic parts applications.our ceramic gears are made of Zirconia, Alumina, Silicon and other advanced ceramics. In stocks and offer customization.
Ceramic pump 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 tubes:
·Excellent physical & chemical stability ·High temperature resistance(up to1750℃)
·Excellent wear & pressure & corrosion& insulation resistance and thermal conductivity..
