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.
