Custom fabrication available upon request.Company ProfileWe have been producing alumina (aluminum oxide, Al2O3) ceramic sheets for more than 15 years, and we adopt strict quality control and use carefully selected high-purity ceramic materials ranging from 95% to 99.8%.The alumina ceramic sheets we produce have excellent electrical insulation, thermal conductivity, and high temperature resistance. One of its unique properties is its excellent surface quality with a surface roughness of up to Ra0.005, which allows it to be used as a substrate for thin film circuits. In addition, it can also be used as an alumina ceramic setter, playing a key role in the sintering process.Common forming methods we use include tape casting, isostatic pressing and dry pressing. We offer a variety of thickness options from small to large sizes. With our complete manufacturing equipment and superb processing capabilities, we have the ability to go from prototype design to mass production in a short period of time.Main characteristics of alumina ceramic sheet1. Good thermal shock resistance, greater than 220 T(oC)2. High thermal conductivity of high purity alumina, up to 30 W/m.k at 25oC 3. Good surface roughness, flatness to be 0.05mm with min. warpage, deformation 4. High dielectric strength, low dielectric constant, and dielectric loss. 5. Laser cutting or precision machining cutting makes tight tolerance.The specification of ceramic sheets1. Materials: 96% alumina, 99% alumina, 99.5% alumina, zirconia, silicon nitride, silicon carbide optional2. Dimensional capability: the side length to be 500mm x 600mm, the thickness can be 0.15mm to 30mm3. Surface treatment: lapping, fine ground, diamond-like polished to be Ra0.05, metallization, glazedOther ceramicsPackaging & ShippingFAQQ: Are you a factory or trading company?A: We are a manufacturer.
