Alumina ceramic washer is a ceramic material with Al2O3 as the main crystal phase. SENCER PRECISION CERAMICS can produce ceramic washers with an alumina content of 99% to 99.5%. The alumina has a compact structure, low activity, and high-temperature stability. The electrical properties are the best, with good mechanical properties, with a Mohs hardness of 9. With the performance of abrasion resistance, corrosion, and heat resistance, excellent vacuum sealing and heat dissipation enable alumina ceramic insulators are widely used in numerous industries.
