Description of Alumina Rods

Alumina Rod has high hardness and good wear resistance. And, Alumina Rod is high temperature resistant and can be used for a long time at a high temperature of 1600 degrees. In addition, it has strong corrosion resistance and good electrical insulation performance. The electrical insulation performance is particularly outstanding at high temperatures, with a withstand voltage of more than 8000v per millimeter of thickness.
