Alumina Threaded Components

Alumina ceramic is the most mature of the engineering ceramics, excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.

Alumina ceramic is the material of choice for alumina wear parts,also an electrically insulating material, with a high electrical resistivity, increasing with is ideal for environments where resistance to wear and corrosive substances are required. Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential. Good chemical stability of alumina leads to high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions.
