Who has information on alumina ceramics
Thread Content
Hey everyone, does anyone have the technical parameters for alumina ceramics? For example, the physical properties of 95% and 98% alumina ceramics
Alumina ceramics are made from high-quality α-alumina, with alumina contents ranging from 95% to 99.7%. It features high hardness, high strength, heat resistance, wear resistance, corrosion resistance, and good electrical insulation properties. It is widely used as wear-resistant, high-temperature resistant, corrosion-resistant, and insulating components in various construction machinery, textile machinery, and electronic appliances.
