Product Description
 | Alumina ceramic insulator: Alumina ceramic insulating components are inorganic non-metallic insulating elements made from high-purity α-Al₂O₃ (alumina) as the main raw material, through precise molding and high-temperature sintering (at 1600–1750℃). |
Alumina ceramic part: Good thermal conductivity, high insulation strength, high electrical resistivity, low dielectric loss, with a dielectric constant generally between 8-10; Lightweight, the density of alumina ceramics is half that of steel, which can reduce equipment load. |  |
 | Application of Alumina Ceramic: It is specifically used for high temperature and high pressure insulation parts, high temperature devices, mechanical wear-resistant parts, sealing rings, plungers, etc. |
Al2O3 Ceramic Features： • Increased life in service • High quality ground surface finish • High flexural strength values • Non-electrically conducting • high temperature resistance |  |
