    Alumina Ceramic Fixing Bracket: High-Reliability Industrial Support Solution

    Alumina Ceramic Fixing Bracket: High-Reliability Industrial Support Solution

    Introduction
    Alumina ceramic fixing brackets are precision structural components made from high-purity alumina (Al₂O₃), offering excellent mechanical strength, wear resistance, and insulation properties. With high hardness, corrosion resistance, and good thermal stability, they are widely used for fixing, supporting, and insulating in various harsh industrial environments.

    Core Advantages

    • High Mechanical Strength: Compressive strength up to 2500 MPa, strong load-bearing capacity

    • Excellent Insulation: Volume resistivity >10¹⁴ Ω·cm, high-voltage insulation resistance

    • High-Temperature Resistance: Long-term service temperature up to 1600°C

    • Wear and Corrosion Resistance: High hardness, resistant to acid and alkali corrosion

    • Dimensional Stability: Low thermal expansion coefficient, high dimensional accuracy

    Main Applications

    • Semiconductor Equipment: Wafer carriers, process fixtures

    • Electrical Power: High-voltage insulation brackets, switch support components

    • High-Temperature Furnaces: Hearth supports, thermocouple protection sleeves

    • Electronic Devices: Circuit board support brackets, heat dissipation substrates

    • Measuring Instruments: Precision instrument brackets, insulation bases
