High precision ceramic shaft rods we produce have good heat conductivity , high thermal conductivity. we offer custom ceramic shaft rod with multi sizes and shape due to the ceramic shaft have a wide range use for industry which have own sizes demands and diameters. Advantages of ceramic shaft rod: - High thermal conductivity - Low coefficient of expansion - High strength - High temperature resistance - Chemical resistance - High resistivity - Small dielectric constant - No toxicity Note: 1.Surface roughness can be reached 0.1�¼m after polished. 2.Size tolerance can be controlled in +-0.10mm with laser machined. 3.Special specifications can be supplied upon requests. Ceramic materials �· 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)
