Al2O3 alumina is a white and opaque high performance ceramic with exceptional physical characteristics. It is extremely temperature resistant and offers a very good mechanical strength. The material, that is also called aluminum oxide, offers an excellent electrical insulation properties, has a low dissipation factor, and a great dielectric strength. These qualities enable the use in high voltage electrical applications.
The mechanical properties of advanced Al2O3 ceramic materials are also remarkable. Hence, aluminum oxide materials are often used when components must withstand strong mechanical wear. They can offer a very good wear resistance. Due to its excellent tribologicals, much longer life times of components and workpieces can be achieved with Al2O3. Furthermore, the chemical strength of alumina is considerable. It can resist most acids and alkalis even at increased temperatures.
Since aluminum oxide materials can be ground using conventional abrasive tools on conventional CNC-machines, complex workpieces based on this special ceramic material can be manufactured. The potential complexity of the components manufactured of aluminum oxide is limited only by the the machinery used, so even very complex precision workpieces can be produced of Al2O3 aluminum oxide.
