Alumina properties High resistance to heat: alumina may be used in an oxidation-reduction atmosphere up to 1650 degC (2900degF), and vacuum environments up up to 2000degC (3600degF).

Wear resistance: Alumina is an extremely durable ceramic that has excellent wear resistance. Alumina is a great choice for products or inserts that require wear resistance.

Electrical insulators: Alumina is a common material used for high-temperature electrical insulation, in particular when it comes to higher purity grades which provide greater resistance.

Chemical resistance: Alumina can withstand strong acids and bases at high temperatures. This makes it an ideal material for chemical resistance applications.

Extreme hardness

Be strong.

High compressive force

High mechanical strength.

At high temperatures, resist strong acid or alkali.

High electrical insulation.

High thermal conductivity

What advantages does alumina offer?

Alumina is an industrially-used wear-resistant ceramic material. This ceramic material has high hardness and wear resistance as well low levels of erosion and corrosion resistance. It also resists biological inertia and high temperatures. Alumina can be highly polished making it ideal for precision sealing such as pistons and pumps. Alumina’s high temperature stability has made it an outstanding high temperature ceramic material. This is the most popular type of advanced ceramics, with purity levels of 95-99.99%.

For what purpose is alumina being used?

Alumina, a hard ceramic that is very wear resistant, can be found in high-quality forms. This ceramic is ideal for making wear-resistant products and inserts. High temperature electrical insulation is a common use of alumina, with particular preference for a better purity that has a lower resistivity. Alumina can also resist strong acids and alkali at high temperatures, making it an excellent choice for corrosion resistance materials.

Some of the most common uses for alumina are:

Substrates as well as electronic components.

Elec. Insulator at high temperatures

High-voltage insulator

Laser tube.

Machine parts

The mechanical seal

High wear axles, precision axles

Roller bearings and ball bearings

Sealing ring

Semiconductor components.

Shoot peening the nozzle.

Tube with thermocouple

Head plate for hose

Valve seat.

Wear parts

Conductors and wires

Ballistic armor
