Product Detail

Material Introdution


Alumina/Aluminium Oxide/Al2O3 is a major engineering ceramic material. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications. Aluminum Oxide Ceramic 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. Alumina based ceramics are by far the largest range of technical ceramics made by UNIPRETEC. Due to the important combination of properties, we have thoroughly researched the behaviour and characteristics of our Alumina products to give you the best possible component.
