High-Strength Alumina Ceramic: Professional Solutions For Precision Bearings, Insulating Components & Corrosion-Resistant Liners
Introduction
Alumina ceramic (Al₂O₃) is a structural ceramic material manufactured from high-purity alumina through modern ceramic processes. It exhibits excellent mechanical strength, outstanding electrical insulation, and remarkable corrosion resistance. Available in purity grades such as 95% and 99%, it is one of the most widely used high-performance ceramics in industrial applications.
Precision Bearings: High-speed spindle bearings, precision instrument bearings
Insulating Components: Circuit substrates, high-voltage insulators, vacuum devices
Chemical Protection: Reaction vessel linings, corrosion-resistant pipelines, mechanical seals
Wear-Resistant Devices: Industrial nozzles, wear-resistant liners, textile ceramic parts
High hardness and wear resistance (Vickers hardness ≥12 GPa)
Excellent electrical insulation (volume resistivity >10¹⁴ Ω·cm)
High-temperature and corrosion resistance (maximum service temperature: 1600°C)
Superior chemical stability (resists acid and alkali erosion)
Cost-effective (better value than specialty ceramics)

Q: How to choose between alumina and silicon nitride ceramics?
A: Alumina is suitable for insulation and general wear resistance applications, while silicon nitride is ideal for higher strength and thermal shock resistance.
Q: What is the minimum achievable aperture size?
A: Using precision machining technology, minimum apertures of 0.3mm can be achieved.
Q: What surface finish can be achieved?
A: After polishing, surface roughness can reach Ra ≤0.1μm.
