1) High hardness.
2) Good abrasion resistance: Alumina ceramic is the material of choice for alumina wearing parts.
3) High resistivity: Alumina is an electrically insulating material.
4) High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkali solutions. The inorganic oxides with extremely stable molecular structure and no electrochemical corrosion results in high corrosion resistance.
