Alumina ceramic, also known as wear-resistant ceramic, is a material that is resistant to wear and tear. Made from alumina (Al2O3) as the main material, with the addition of other additives, and sintered at over 1600 degrees Celsius. It has high hardness and wear resistance, and is widely used in various industries.

The forming methods of alumina ceramics generally include dry pressing, injection molding, isostatic pressing, injection molding, and casting molding. Producing products with different ceramic shapes, complexities, and accuracies requires different molding methods.

The hardness of wear-resistant ceramics is second only to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel. Its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. Using wear-resistant ceramic lining on equipment can extend its service life by at least ten times.

The aluminum content of alumina ceramics is generally between 90% and 99.9%, with over 95% belonging to high alumina ceramics. The higher the aluminum content of alumina ceramics, the more stable their performance and the better their wear resistance.
