Aluminiumoxd (Al2O3) products are among the strongest and hardest of all ceramic materials. They also have a high dielectric strength and at elevated temperatures, such as those encountered in many applications, their electrical resistance is excellent.

Alumina ceramics also feature:

very high mechanical strength

high thermal conductivity

high resistance to chemical

corrosion attack at room

elevated temperatures

Further, this valuable class of materials can be made extremely hard - second only to diamond on the Mohs’ scale,
