The description of alumina ceramic plate

Alumina (Al2O3) is an technical ceramic that offers high hardness, compressive strength, excellent electrical insulation and good thermal properties. Since the unmatched cost and performance, alumina is a prime engineering material, which makes it applicable for a board range of uses.

Alumina ceramic plate is commonly shaped by Isostatic pressing, dry pressing, tape casting and hot pressing, then sintered under very high-temperature to form the dense ceramic body. Our factory offers small-size to large-size alumina ceramic plates in customized thickness range from 0.25mm to 30mm, the max. diameter can be 500mm. 

Besides, we could manufacturer a variety of complicated shapes, including convex, concave and so on. In order to meet customers' stiff application, a precision flat grinding is needed to reach the flatness to be 0.002mm and the the tolerance of thickness to be 0.01mm. Additionally, we offer other secondary processes, such as diamond - like polishing, lapping, cutting, metalizing for ceramic to metal bonding and CNC machining to reach customers' specific needs.
