Wear Resistance 95% Al2O3 Substrate , Aluminum Oxide Plate For Insulation
1. Description
Alumina ceramic part is made from 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.
