Aluminium oxides (Al2O3) are used for wear-resistant components and also for isolations used in the electronic industries. They are also used in chemical industries for protection against corrosion and for filters. They are used in measurement and test engineering. And they are used to protect thermocouples and are perfect for the use in high temperature areas, like i.e. burner nozzles. Also Aluminium oxides are used as implants in human medicine.
To summarize: Aluminium oxide combines following characteristics:
- high strength and hardness
- high resistance to temperature changes
- high resistance to wear
- high resistance to corrosion
