Product Description

Refractory Machinable Custom 99.5% Alumina Ceramic Plate for Industrial

Description of alumina ceramic plate
We have been producing alumina (Al2O3) ceramic substrates for over 15 years under rigorous quality control with carefully selected high purity ceramic materials that ensure stable and consistent quality and excellent properties.
These alumina substrates have extraordinary properties of electrical insulation, thermal conductivity, breaking strength and high-temperature resistance.  Furthermore, one of the unique properties is its surface roughness. We can provide the ceramic substrate which is excellent in adhesion with a thin film and thick film metallization due to fine particles.
The main forming method we use is tape-casting, we are dealing with a variety of selection of thickness from 0.25mm to 20mm. Besides, we support prototyping case to mass production.

Specification of alumina ceramic plate
● Material : 96% alumina, 99% alumina, 99.5% alumina, zirconia optional
● Dimensions: Side length max. 300mm x 400mm, Thickness can be 0.2mm to 20mm
● Surface treatment:  Fine ground, Well-polished, Metallization, Glazed
● The checklist of standard size with the stock level in 96% alumina:

The advantages of alumina ceramic substrate: 
1. High thermal conductivity, up to 24 W/m.k at 25℃                       
2. Good thermal shock resistance, greater than 220 T(℃)           
3. Good surface roughness, flatness to be 0.05mm
4. High dielectric strength, low dielectric constant and dielectric loss.                       
5. Laser cutting or precision machining cutting makes tight tolerance.

Typical applications of alumina ceramic substrate:
LED packages, Power modules, Substrates for chip resistors, HIC substrates for heat dissipation, FAX substrates for thermal printer head, Substrates for automotive parts, Substrates for general thick film application, Substrates for sensor parts, Substrates for electronic devices
