UNIPRETEC is professional in providing aluminum oxide plates, which is made of Alumina(Al2O3). As a technical advanced ceramic material, alumina is most commonly used. And yet there are variations in standards of purity and production methods. What does aluminum oxide ceramic plate from UNIPRETEC CERAMIC TECHNOLOGY constitute? Our aluminium oxide ceramic plate has a very high purity up to 99.8%. We make efficient use of the good properties of the material with our different operation including CIP(Cold Isostatic Pressing), dry pressing, tape casting(specially for making aluminium oxide thin plate), slip casting, extrusion... These include high hardness and strength, stability of the temperature and, in particular, resistance to abrasion. Alumina is ideal for use in countless industrial and commercial applications, such as mechanical and electrical engineering for wear and corrosion liners, insulating substrates... Additionally, for high-performance mills or complex components for the aerospace industry, the material provides the best conditions for customer-specific components, to name only a few areas of use.
