Alumina ceramics are the industrial ceramic oxides of Aluminum which are used in many different industries for their hardness and resistance to abrasion, as well as their superior heat resistance.

Alumina is an excellent high temperature ceramic material because of its high temperature stability. It is one of the most commonly used advanced ceramics.

Features:

●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);

●High hardness (15 to 19 GPA);

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

●Low density (3.75 to 3.95 g/cm3);

●The operating temperature is 1650℃ without mechanical load;

●Bioinertness, food compatibility.

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
