Alumina Ceramics Bushing Bearing Anti-wear Long service life Bushing

Alumina ceramic, also known as aluminum oxide or Al2O3, is a ceramic material composed of aluminum and oxygen. It is renowned for its remarkable combination of properties, including high hardness, excellent wear resistance, exceptional thermal stability, and good electrical insulation. These characteristics make it an ideal choice for various demanding applications

Material

95,96,98,99,99.5,99.7 Aluminum Oxide or Al2O3

Advantages

Chemical Resistance

They are highly resistant to chemical corrosion and can endure exposure to many aggressive chemicals, acids, and alkalis without degradation. This property is advantageous in chemical processing and the handling of corrosive substances.

High Hardness

Alumina ceramics are renowned for their exceptional hardness, ranking just below diamonds on the Mohs scale. This property makes them highly resistant to abrasion and wear, allowing them to maintain their integrity in demanding environments.

Excellent Mechanical Strength

They exhibit impressive mechanical strength, ensuring they can withstand heavy loads and mechanical stress without deformation or failure. This property is crucial in applications where structural integrity is paramount.

Exceptional Electrical Insulation

Alumina ceramics are excellent electrical insulators, making them indispensable in electronic and electrical applications. They can efficiently prevent the flow of electricity, making them suitable for insulating components and substrates.

Superb Thermal Stability

Alumina ceramics excel at maintaining their structural and mechanical properties at high temperatures, withstanding temperatures well above 1,000 degrees Celsius. This characteristic is invaluable in applications involving extreme heat.

Low Thermal Expansion

Alumina ceramics have a low coefficient of thermal expansion, meaning they do not significantly expand or contract with changes in temperature. This property contributes to their dimensional stability in varying thermal conditions.
