Alumina Ceramic Disc is a kind of ceramic material with alumina as the main material, which is manufactured through specific work. Due to its excellent conductivity, high-temperature resistance, and mechanical strength, Alumina Ceramic Disc is mainly used in thick film integrated circuits and valves

Because the ceramic material has very small thermal deformation, lightweight, and much higher bonding strength than the metal, with excellent corrosion resistance, so Alumina Ceramic Valve Disc can better adapt to high wear, strong corrosion, and other adverse conditions.

Generally, the crystal ion radius of alumina ceramic material is small, and the ion electricity price is high and the coordination number is large. These intrinsic properties determine the compressive strength, wear-resistance, and hardness of ceramic material. Therefore, Mingxing Ceramics' Alumina Ceramic Disc is suitable for valves.
