Aluminum oxide (Al2O3 or Alumina) is a white opaque high performance ceramic with many interesting physical properties. Alumina is extremely temperature resistant and it has a very good mechanical strength. Aluminum oxide offers extraordinarily good electrical insulation properties. Alumina has a low dissipation factor and a strong dielectric strength which enables many electrical applications such as insulators or as a dielectric, etc. But also the mechanical characteristics of aluminum oxide are a noteworthy feature of this ceramic material. Parts that are made of aluminum oxide materials are often used when exposed to mechanical wear and show a very good wear resistance. Due to the good tribological properties much longer life times of workpieces can often be achieved with Al2O3. Since aluminum oxide materials can be ground using conventional abrasive tools on conventional CNC machines, complex workpieces made of this special alumina material can be manufactured. The potential complexity of the components that can be manufactured of aluminum oxide is limited only by the technical limits of the machinery used, so even very complex and very precise workpieces can be produced of Al2O3 aluminum oxide.
