Mechanical Ceramic Rings Alumina Ceramic Ring Wear Resistant
Aluminum oxide (alumina) is the workhorse of advanced technical ceramics. It has good mechanical and electrical properties, wear resistance and corrosion resistance. It has relatively poor thermal shock resistance. It is used as an electrical insulator for a number of electrical and electronic applications, including spark plug insulators and electronic substrates. It is also used in chemical, medical and wear applications.
