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.
All alumina ceramic disc could be customized according to your data requirements and drawings.
2. Features and advantage of alumina ceramic disc
1.Great mechanical strength
2.Low thermal conductivity
3.High heat resistance
4.High softening temperature
5.Small thermal expansion coefficient
6.Good cold-resistance heat-resistance
7.Resistance to acid and alkali corrosion
8.Long service life
