Alumina properties High resistance to heat: alumina may be used in an oxidation-reduction atmosphere up to 1650°C (2900°F), and vacuum environments up up to 2000°C (3600°F).
Wear resistance: Alumina is an extremely durable ceramic that has exceptional 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, making 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 acids 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 wear and hardness as well as low erosion, high resistance to heat, high resistance to corrosion, resistance to rust and biological inertia. Alumina can also be extremely polished 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 widely used advanced ceramic with an average purity 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 insulators are often made from alumina, and especially higher quality grades with better resistivity. Alumina can also resist strong acid and alkali at elevated temperatures, making it an excellent choice for corrosion resistance materials.
Alumina can be used for many purposes, including:
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
Bearings in roller or ball.
Sealing ring
Semiconductor components.
Shoot peening the nozzle.
Thermocouple tube.
Head plate for hose
Valve seat.
Wear parts
Conductors as well as wires
Ballistic armor
