Alumina ceramic screws:

Ceramic screws are made of zirconia, alumina and other materials. They have relatively stable physical and chemical stability. The physical stability is mainly manifested in the aspects of high and low temperature resistance, insulation, antimagnetic, and wear resistance. The main surface of chemical stability is Corrosion and oxidation resistance. Among oxides with a melting point of more than 2000°C, alumina is the most flexible and cheap material. Alumina ceramics is the ceramic material with the widest application, the widest application and the largest output among the oxide ceramics. There are three crystal forms of zirconia ceramics, namely monoclinic zirconia, tetragonal zirconia and cubic zirconia, and these three forms will change with the temperature.
