    Alumina Ceramic: High-Performance Material Solution For Precision Industry

    Alumina Ceramic: High-Performance Material Solution for Precision Industry

    Introduction
    Alumina ceramic (Al₂O₃) is an advanced engineering ceramic material with alpha-alumina as the main crystal phase. Manufactured using high-purity raw materials through high-temperature sintering process, it is renowned for its excellent electrical insulation, extremely high mechanical strength, and outstanding corrosion resistance. It is an indispensable key material in precision instruments, mechanical equipment, and chemical industries, providing reliable performance guarantee for high-end equipment.

    Applications

    1. Precision Instruments: Insulating pillars, circuit substrates, vacuum seals, measuring instrument guides

    2. Mechanical Field: Bearings, bearing sleeves, mechanical seal rings, wear-resistant liners

    3. Chemical Equipment: Corrosion-resistant pipelines, valve linings, pump components, reactor linings

    Advantages

    1. Excellent Insulation Performance: Dielectric strength up to 15-20kV/mm, volume resistivity >10¹⁴Ω·cm

    2. Outstanding Mechanical Properties: Compressive strength ≥2000MPa, Vickers hardness ≥1500HV

    3. Exceptional Corrosion Resistance: Resistant to acid and alkali corrosion, excellent chemical stability

    4. High Heat Resistance: Long-term service temperature up to 1400℃

    5. Low Wear Rate: Wear resistance is more than 10 times that of metal materials
