Alumina Ceramic Insulator is made of a ceramic material with Al2O3 as the main crystal phase. SENCER PRECISION CERAMICS can produce ceramic Insulators with an alumina content of 99% to 99.8%. 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 the auto and vessel, and aircraft industry.
