Product Description

We have been making alumina (Aluminum oxide, Al2O3) ceramic sheets for over 12 years under rigorous quality control with carefully selected high-purity ceramic materials ranging from 95% to 99.8%.

All these alumina sheets offer extraordinary properties of electrical insulation, thermal conductivity, breaking strength, and high-temperature resistance.  Furthermore, one of its unique properties is its superb surface roughness to be Ra0.2 which results in excellent adhesion strength with a thin film and thick film metallization due to fine particles. Also, it can play a critical role in the sintering process which works as an alumina ceramic setter.

The regular forming methods we use include tape-casting, isostatic pressing, dry pressing. We are dealing with a variety of selection of thicknesses from small-size to large-size capability. With our comprehensive types of manufacturing types of equipment, we have the capability from prototyping to mass production in the short term.
