    Electrical Metallized Ceramic Insulator , Ceramic Holder High Bonding Strength

    High Bonding Strength Metallised Alumina Ceramic Holder for Electrical

    Ceramic metallization plays a key role in ceramic to ceramic, ceramic to metal jointing technology of electrical, electronic, medical, sensors and high-vacuum packaging applications.

    Our factory has been specializing in molybdenum/tungsten thick film metallization on 95%, 99% and 99.5% alumina ceramics. Also, we have developed metallizing methods on other technical ceramic materials, like zirconia, and beryllia. We utilize electro or electroless nickel/silver/gold plating as the preferred deposition over metallization. The result in a system easily brazed with copper-silver, pure copper, gold and other

    common braze alloys.


    Metallization types:

    ● Ceramic body + Silver (Ag) plating

    ● Ceramic body + Molybdenum-Manganese ( Mo-Mn) metallization

    ● Ceramic body + Molybdenum-Manganese ( Mo-Mn) metallization + Nickle ( Ni ) plating

    ● Ceramic body + Tungsten ( W ) metallization + Gold ( Au ) plating

    Special types are available according to customer's drawings or samples


    Main characteristics of Metallized ceramic isolator

    ● Min. electric resistance and vacuum tightness, and less than 1×10-11 Pa•m3 / s

    ● High bonding/brazing strength, It can be up to 150 MPa after brazing

    ● High mechanical strength, flexural strength can be up to 338 MPa

    ● High insulation, anti-chemical and anti-aging. It will be free of rust forever


    Applications:
    Vacuum interrupters, Vacuum circuit breakers, Feed-through insulators, Headers, High-power receptacles, Insulating discs, Insulator rings and cylinders, Precipitator products, Power switches, Traveling wave tubes, Windows, Power grid tubes, X-ray tubes
