Aluminum oxide (Al2O3) has an exceptional set of properties:
All these combinations make the material irreplaceable in the manufacture of corrosion-resistant, wear-resistant, electrical insulating and heat-resistant products for a variety of industries.
There are two main types of aluminum oxide:
Dense Aluminum Oxide (Al2O3)
This material is used in production of responsible and mechanically loaded products, i.e. mainly as engineering and structural ceramics. The material has excellent corrosion-resistant, wear-resistant, electrical insulating and heat-resistant properties, in addition to resistance to thermal shock. If a thermal shock is present during operation, it is recommended to use refractory materials.
There are several modifications of dense aluminum oxide depending on the content of the main phase and admixtures, which differ in strength and chemical resistance (ALOX-AP, ALOX-HP).
