Alumina Ceramic Materials Overview
Alumina (Al2O3) ceramic is a versatile, high-performance material known for its exceptional strength, durability, and electrical insulating properties. Available in a range of purities, it caters to industries requiring wear resistance, corrosion protection, and high-temperature stability. Below are the key benefits and applications of various alumina grades:

  • 95% Alumina (A950)

    • Excellent mechanical strength and electrical insulation
    • Suitable for high-temperature components (up to 1500°C)
    • Used in pump plungers, shafts, cylinder liners, electrical insulators, and high-voltage components
  • 96% Alumina (A960)

    • Ideal for ceramic substrates in electronic applications
    • Offers high thermal conductivity, low CTE, and excellent electrical insulation
    • Widely used in thin-film and thick-film electronics, and reliable PCB substrates
  • 99% Alumina (A990)

    • Enhanced wear, corrosion, and temperature resistance (up to 1650°C)
    • Excellent material for sintering furnace plates and complex components
    • Used in pressure washer pistons, metering pumps, and seal rings
  • 99.8% Alumina (A998)

    • Superior surface finish (Ra 0.05μm) with extreme hardness and inertness
    • Ideal for applications requiring ultra-pure material and high-strength conditions
    • Commonly used in demanding environments with high operating temperatures and purity requirements

These materials help professional buyers select the most suitable grade for specific industrial applications, ensuring performance optimization, cost-effectiveness, and longevity.
