Alumina is the most cost effective material and it is widely used due to its resistance to corrosion, abrasion and wear. It has a good combination of mechanical and electrical properties. Al203 is excellent as electrical insulator and it is gas tight.
Aluminum Oxide can be produced by hot pressing, dry pressing or sintering and in a wide range of purities. Combining additives, its properties can be enhanced for the most demanding high temperatures. In addition, aided by metallizing and brazing techniques, Aluminum Oxide can be joined to metals.
