    Ceramic Nitride Silicone Si3N4 Pin For Welding Nut


    1 . Description:

    Silicon nitride ceramics have good tribological properties and excellent fracture toughness, which makes it be predestined for applications as balls and rolling elements for light and extremely precise bearings, heavy-duty ceramic forming tools and automotive components subject to high stress. And the good thermal shock resistance and high temperature resistance is exploited in welding processes.



    2 . Advantages of silicon nitride ceramic dowel pin

    High hardness and wear resistance, both impingement and frictional modes

    Superior thermal shock resistance

    Low thermal expansion
    Electrical insulator
    Good oxidation resistance
    Good chemical corrosion resistance
    Wear resistant
    High stiffness


    3 . Applications of silicon nitride ceramic

    ✔ Welding pins, jigs, fixtures and nozzles

    ✔ Turbine blades

    ✔ Bearing balls and rollers
    ✔ Cutting tools
    ✔ Valves, turbocharger rotors for engines
    ✔ Diesel engine glow plugs
    ✔ Molten metal handling
    ✔ Thermocouple sheaths
