Excellent Thermal Stability Aluminum Oxide Ceramic Plate High Heat Resistance
High mechanical strength high wear resistance alumina ceramic disc
1. Description
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 ceramic is generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
