95% Al3O2 Alumina Ceramic shafts and Bearings Circulation Pump Components Wear Resistance
Advanced ceramic components made from alumina ceramics, zirconia ceramics, silicon carbide etc are specially abrasion resistance, remain a good performance for a long time in machinery, shield pumps, circulating pumps, cleaning machines/devices, because they are much better than metal components in terms of friction resistance, corrosion resistance, high temperature resistance, shock resistance, thermal resistance, acid&alkali resistance. For example, circulating heating pumps with alumina ceramic parts such as alumina ceramic shafts, alumina ceramic bearings can last more than 15 years in a stable conditions.
Also, because of their high hardness(88-96HRA), good anti-abrasion and anti-corrosion propertities, they are widely used in fields as pharmaceutical filling lines, energy industry, solar power industry, electronics devices, textile machines, military bullet proof armours, etc.
These advanced alumina ceramic parts, usually also called technical ceramics can be formulated and sintered into different shapes with fine dimensions, with or without machining, especially alumina ceramic shafts and bearings, are already widely adapted in several leading pump manufactures, as well as other different machinery or equipments producers.
Suzhou Jingci Superhard Materials Co., Ltd.(www.fineceram.com) has an experienced production practice in these varial ceramic parts since it was founded in 1999, and can surely provide the alumina ceramic parts you need.
