    High Desity 99.9% Alumina Ceramic Plate , Aluminum Oxide Ceramic Insulators



    Aluminum oxide insulating washers have a dielectric strength of approximately 21.7 x 10³ volts/mm for 0.76mm material and 16.9 x 10³ volts/mm for 1.57mm material. The thermal conductivity of aluminum oxide is 15.06 W/mK @ 75°. Aluminum oxide has unique thermal conductivity qualities and features low loss factors at high frequencies. It has high compressive strengths, high volume resistivity, low thermal expansion and it resists radiation.

    Our alumina substrate has well-balanced properties of insulation, thermal conductivity and breaking strength. Moreover, one of the unique properties is its surface roughness. We can provide the ceramic substrate which is excellent in adhesion with a thin film and thick film metalization due to fine particles.

    ■Good smoothness / flatness with less porosity. Excellent in adhesion with thin film and thick film materials.
    ■Less variance in outline, plate thickness, slit pitch, etc.
    ■Minimal warpage, bending, and undulation.
    ■Physical and chemical properties are stable even under a hot environment. Excellent in thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.
    ■Superior mechanical strength. Products with higher mechanical strength are also in our lineup.
    ■Excellent resistance against oil and chemical.
    ■Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.
    ■Stable breaking strength, and less variance in shape or dimensions.
    ■The high reflective substrate, especially suitable for optical applications such as LED, is also available.


    Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. Alumina Plates and Disks are available in different dimensions and thicknesses. Call for custom shapes and sizes.
