High Purity 99% Alumina Ceramic Sleeve Industrial Ceramic

High Purity 99% Alumina Ceramic Sleeve Industrial Ceramic

Alumina ceramic sleeves, composed of 99% pure aluminum oxide, are high-performance components renowned for their exceptional mechanical and physical properties. These bushings exhibit remarkable hardness, wear resistance, and thermal stability, making them ideal for applications in various industries such as automotive, aerospace, and heavy machinery. With a high melting point and excellent electrical insulation, 99% alumina ceramic bushings are also favored for electrical and electronic applications where high-temperature resistance and dielectric strength are critical. Their chemical inertness ensures compatibility with a wide range of materials and environments, contributing to their longevity and reliability in service. Furthermore, their low coefficient of thermal expansion helps maintain dimensional stability under varying temperature conditions, a feature that is particularly beneficial in precision engineering.

Main Features:

1. High hardness
