Alumina ceramic has high hardness, good wear resistance and corrosion resistance, high temperature resistance. Alumina ceramics have been more and more widely used in modern society because of its superior performance to meet people's needs.

● Alumina ceramics is a very cost-effective precision ceramics.

●Can be used up to 1650°C environment.

● Hardness up to 15.7Gpa, very wear-resistant.

●Excellent electrical insulation (1×1014 to 1×1015 Ω cm);

●Medium to ultra-high mechanical strength (300 to 630 MPa);

●Very high compressive strength (2000 to 4000 MPa);

●Moderate thermal conductivity (20 to 30 W/MK);

●Low density (3.75 to 3.95 g/cm3);

Alumina ceramics are the most common advanced ceramic materials.As an excellent ceramic material, high purity alumina ceramics have been widely used in many industries. 

The material has excellent properties in electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion. 

Therefore, alumina ceramic products are used for many industries, such as:

⭐️Shafts and plungers in high wear environments

⭐️Roller and ball bearings

⭐️Wear-resistant lining

⭐️Semiconductor parts

⭐️Machine component

⭐️High temperature electrical insulator

⭐️High voltage insulator

⭐️Wires and conductors

⭐️Mechanical seal
