Where is alumina used

Contact us today! Is aluminium oxide toxic to humans? What can aluminium oxide be used for? Alumina injection molding is the manufacturing process that provides specialized custom components for use in different industries, but their main applications are in: Medical industry : The chemical properties of aluminium oxide, as well as its hardness and bio-inertness make it a suitable material for various medical applications, including bionic implants, tissue reinforcement, prostheses, hip replacement bearings, etc.

Protective equipment : The lightweight qualities and the strength of aluminium oxide make it a great choice for enhancing body and vehicle armors, as well as creating synthetic-sapphire bulletproof ballistics and windows.

Electrical industry : The high boiling and melting points of aluminium oxide make this compound a great choice for manufacturing of high-temperature furnace insulation, as well as electrical insulators. Alumina is also widely used in the microchip industry. Gem industry : Aluminium oxide is used in the process of formation of sapphires and rubies.

In its crystalline form, or corundum, alumina is the base element for the creation of these two precious gems. And although there is no such thing as a truly unbreakable glass, alumina has been studied for its potential in creating this very thing.

These materials are crafted for especially harsh applications that require increased wear resistance, thermal stability, and many of the other characteristics that make alumina such a valuable component of so many products.

Alumina is used in bearings for hip replacements, in prosthetic limbs , bionic implants, prosthetic eye substitutes, tissue reinforcements, and a host of dental implants. It is also used in the medical industry outside the body — in lab equipment and tools like crucibles, furnaces, and other labware. Alumina is adept at creating military and civilian protective equipment due to its strength and lightweight qualities.

Body armour, vehicle armour, and aircraft armour are all created using alumina, with the latter being the largest market for the material in this field. It is also used in making bulletproof windows and ballistics for stationary objects. With a high melting and boiling point, as well as excellent thermal resistive properties, alumina powder is ideal for electrical insulators.

It is also an essential component in microchips and is a great material to use for insulating heatsinks. Alumina powder is an important material used in the formation of rubies and sapphires — corundum, which is its crystalline form, is the base element for these and other gems.

Alumina is also used as a polishing powder for some of the most difficult gems, including those with hardness levels of 8. With alumina being a chemically inert substance, it can be used as a filler in plastics, bricks, and other heavy clayware such as kilns. Also, due to its abrasive nature, it can be used as sandpaper for construction activities. Alumina can be used in a wide variety of industrial applications, from piping components such as elbows, tees, and straight pipes, to hydro cyclones, reducers, nozzles, and valves.

It is also a very useful material for machining tools, cutting tools, thermocouple sheaths, and wear-resistant pump impellers.

Alumina is a fairly common compound that can be sourced from many areas of the world. Many specifications can be sourced directly from Matmatch , as well as material traders in Europe and around the world, depending on what is needed.

These gemstones can be produced synthetically and are occasionally referred to as alumina. This term is usually limited to the synthetic gemstones used in the metallurgy, ceramics and chemical processing industries. Naturally formed rubies and sapphires are two of the four precious gemstones, emeralds and diamonds being the other two. Increasingly, aluminum foil is being merged with flexible films to create lightweight, flexible packages.
