What is alumina used for?

Alumina properties High resistance to heat: alumina may be used in an oxidation-reduction atmosphere up to 1650degC (2900degF), or in vacuum environments as high as 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: This is a common use of alumina, in particular for high purity grades which provide higher resistivity.

Chemical resistance: Alumina can withstand strong bases and acids at high temperature. This makes it an excellent choice for applications that require resistance to corrosive substances.

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 exceptional hardness, wear resistance, low temperature resistance, corrosion resistance, biological inertia, and high heat resistance. Alumina can be polished very finely, making it suitable to precision seal applications, such as pistons and pumps. Alumina’s high temperature stability has made it an outstanding high-temperature ceramic. 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 insulator is a common use of alumina, in particular a more pure grade with a better resistivity. Alumina can also resist strong acids and alkali at high temperatures, making it an excellent choice for corrosion resistance materials.

Here are some common uses of alumina:

Substrates as well as electronic components.

Elec. Insulator at high temperatures

Insulator with high voltage.

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.

Thermocouple tube.

Head plate for hose

Valve seat.

Wear parts

Conductors, wires

Ballistic armor
