Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.
1). Excellent insulation, security, long working life.
2). High temperature resistance
3). Resistance to electric breakdown
4). Stand wear and tear
5). High strength
6). Corrosion resistance
7). Good compactness
8). HIgh hardness
