Introduction of hardness, classification and cutting of alumina industrial ceramics 1.Introduction to the hardness of alumina industrial ceramic The hardness of alumina industrial ceramic is extremely high. Whether it is polycrystalline alumina industrial ceramics or single crystal alumina industrial ceramics, it has a high hardness of stainless steel. Due to the hardness of ceramic brackets, it can reach more than nine times that of stainless steel and enamel. So when our teeth are in contact with ceramic brackets, the enamel will be [...]
