Alumina Ceramic Balls

Alumina Ceramic Ballsmerits

The core advantage of alumina ceramic ball is high hardness and strong wear resistance. Alumina ceramics itself has a high hardness, in the long-term rolling friction or high-speed operation, still be able to keep the surface clean, not easy to produce wear, scratches or deformation. Ceramic ball can significantly extend the service life, and maintain long-term operational accuracy and stability.

Description

Aluminum oxide ceramics球merits

Alumina ceramic ball is a high-performance ceramic ball made by molding, sintering and other high-temperature processes. Its structure is dense, high degree of sphericity, the surface has been precision grinding or polishing treatment, with stable physical and chemical properties. Commonly used in precision machinery, chemical filler, bearing rolling body, wear-resistant support and functional parts in high temperature environment.

Ultra-high hardness, excellent wear resistance
Stable high temperature resistance
Excellent electrical insulation properties
Moderate density and good operational stability

Aluminum oxide ceramics applications

Alumina ceramics are the most common advanced ceramic material and more traditional. As an excellent ceramic material, high purity alumina ceramics have been widely used in many industries. The material has excellent properties in terms of electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion. Therefore, alumina ceramic products are ideal for many industries such as:

Shafts and plungers in high wear environments
Roller and ball bearings
Wear-resistant lining
semiconductor part
Machine components
High temperature electrical insulators
High-voltage insulators
Wires and conductors
mechanical seal
