Black Ceramic Substrate / Black Ceramic Block :

Alumina substrates can withstand high temperature and maintain high strength and hardness. Alumina plates also have superb performances in electrical insulation, high chemical resistance and low thermal expansion. We have various sizes of semi finished shapes in stock and are able to conduct custom manufacturing for all kinds of alumina components.

Black Ceramic Substrate / Black Ceramic Block Specifications

Quality assurance:

1. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
2. Good wear resistance : Alumina eramic is the material of choice for wear parts.
3. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.

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.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
