Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance, but relatively low strength and fracture toughness. Alumina ceramic is generally white but may also be pink or ivory. The color is derived from either the sintering additives or impurities in the raw materials.
Mingrui ceramic manufacture and provides alumina ceramic components for a wide range of application like Mechanical Equipment, Electronic & Electrical, Oil Drilling, Medical, Chemical Industry etc. According to actual application and customer's requirement, the purities vary from 95%-99.7% and the forming methods will be different. The forming methods applied in our plant include dry pressing, isostatic pressing, injection moulding, extrusion moulding. With experienced engineers and talented workers, we are confident to offer high quality, high precision, complex components for customers worldwide.
