1.Product description of alumina ceramic disc

Ceramic disc are used in many electronic applications where a thin insulating layer of thermally stable material is required to conduct heat away from electronic components whilst electrically insulating them, and material is 96% alumina, zirconia, silicon nitride and aluminum nitride, All our substrates are produced by laser cutting and surface grinding.

Properties with excellent insulation, high mechanical strength, high thermal conductivity, low expansion coefficient, small dielectric constant, high-temperature resistance, excellent erosion and wear resistance, good quality in chemical shock heat and cold.

All alumina ceramic disc could be customized according to your data requirements and drawings.
