With more than 15 years of experience in producing alumina (aluminum oxide, Al2O3) ceramic sheets, we adopt strict quality control and use carefully selected high-purity ceramic materials ranging from 95% to 99.8%.

Our alumina ceramic sheets feature excellent electrical insulation, thermal conductivity, and high temperature resistance. Its unique surface quality with a roughness up to Ra0.005 allows for use as a substrate for thin film circuits and as an alumina ceramic setter in sintering processes.

• Good thermal shock resistance, greater than 220 T(ºC)
• High thermal conductivity of high purity alumina, up to 30 W/m.k at 25ºC
• Excellent surface roughness and flatness (0.05mm) with minimal warpage
• High dielectric strength, low dielectric constant, and dielectric loss
• Precision laser cutting and machining for tight tolerances

• Materials: 96% alumina, 99% alumina, 99.5% alumina, zirconia, silicon nitride, silicon carbide optional
• Dimensional capability: Side length up to 500mm x 600mm; Thickness from 0.15mm to 30mm
• Surface treatment: Lapping, fine ground, diamond-like polished to Ra0.05, metallization, glazed

We focus on high-performance special ceramics such as alumina and zirconia, widely used in various industrial environments requiring high wear and corrosion resistance.
