I. machinery

The bending strength of alumina ceramic products can reach 250Mpa and that of hot pressed products can reach 500MPa. The Moh’s hardness of alumina ceramics is up to 9. In addition, alumina ceramics has excellent wear resistance. Therefore, alumina ceramics are widely used in the manufacture of cutting tools, ball valves, grinding wheels, ceramic nails, bearings, etc., among which alumina ceramics cutting tools and industrial valves are the most widely used. Such as: pure alumina ceramic tool

The optimal cutting speed of alumina ceramic tool is higher than that of a metal alloy tool, which can greatly improve the cutting efficiency of different materials.

II. Medicine

In medicine, alumina is used to make artificial bone, artificial joints, artificial teeth and so on.

Advantages: alumina ceramics have excellent bio-compatibility, biological inertia, physical and chemical stability, high hardness, high wear resistance. It is the ideal material for the preparation of artificial bone and artificial joint.

III. Chemical industry

Alumina ceramic is also widely used in chemical industry, such as alumina ceramic chemical filler ball, inorganic micro-filtration membrane and corrosion-resistant coating, etc., among which alumina ceramic membrane and coating are the most popular in research and application.

IV. Electronics / power

In terms of electronics and electric power, there are various alumina ceramic plates, substrates, ceramic films, transparent ceramics and various alumina ceramic electrical insulating ceramics, electronic materials, magnetic materials, etc., among which alumina ceramics are most widely used.
