Alumina ceramics have a series of excellent properties such as high hardness, high wear resistance, corrosion resistance and high temperature resistance. It is widely used in textile, petroleum, chemical, construction and electronics industries, and is currently used in oxide ceramics, large production and sales, high temperature resistant ceramic materials. Main alumina ceramic grade: A-100, A-200, AZ-100 several. Used to produce: ceramic nails, ceramic seals, ceramic ball valves, cutting tools, ceramic plunger, bearing, circuit board, valve seat, shell, etc.
