Product Description

Product Description

Industrial Application 99% Alumina Ceramic Precision Parts Ivory Color Al2O3 Insulation Sleeve

Our 99% alumina ceramic components are manufactured from high purity aluminium oxide (Al2O3) raw material, delivering stable mechanical, thermal and electrical performance for diverse industrial operating conditions.

99% Alumina Ceramic Precision Parts 

As a widely-used advanced technical ceramic material, 99% alumina ceramic balances high mechanical strength, excellent electrical insulation and reliable thermal stability, which makes it a preferred material choice for electrical insulation, high temperature equipment, precision instrumentation and mechanical wear resistant assemblies.

Made of 99% high purity alumina ceramic, the material features ivory white appearance.

All items can be customized according to customer drawings or samples, including tubes, bushes, discs, blocks, special-shaped structural parts and other non standard ceramic components.

 

99% Al2O3 Ceramic Features & Advantages

Superior electrical insulation: High volume resistivity and high dielectric strength deliver safe insulation performance under high-voltage working conditions.

Good mechanical property: High hardness and flexural strength bring anti-wear and anti-impact capacity for extended service life.

Fine thermal performance: Stable thermal conductivity and good heat-resistant capability adapt well to high-temperature working environments.

Zero water absorption: Dense sintered microstructure prevents performance shifts triggered by moisture absorption.

Customizable solution: we can produce parts with different sizes, hole-structures, outlines and precision dimensions.

Surface treatments like fine grinding and polishing can be offered upon request.
