Product Description

The Most Well-known Oxide Ceramic Material

Aluminum Oxide (Al2O3)

Alumina or aluminum oxide (Al2O3) is a major engineering material. It offers a combination of good mechanical properties and electrical properties. It is used more often than any other advanced ceramic material.

A wide variety of ceramic processing methods can be applied including machining or net shape forming to produce a wide variety of sizes and shapes of component. In addition, it can be readily joined to metals or other ceramics using metallising and brazing techniques.

Alumina based ceramics are by far the largest range of advanced ceramics made by HaoRui. HaoRui offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.
