China Industrial Alumina Ceramic Block

Electrical insulation. Most ceramic materials are excellent electrical insulators. Alumina, for instance, with a room-temperature volume resistivity of more than 10 ¹⁴ohm-cm and a melting point of 2,090°C, is ideal for spark-plug insulators.

Product Description

1. Material: 99%Alumina
2. High intensity
3. Wear resistance, excellent performance
4. Shaped as your designing and requirment
