Alumina

The most common material used for structural ceramic parts is Axim’s alumina. It is used in applications from aerospace to medical, to bearings to analytical instrumentation. Axim’s high purity alumina ceramics lends itself well to corrosive environments.

Aluminium Oxide, Al2O3 is a major engineering material. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications. Alumina can be produced in a range of purities with additives designed to enhance properties. 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.

Due to the important combination of properties, Axim has thoroughly researched the behavior and characteristics of our Alumina products to give you the best possible component.
