Aluminium Powder

Aluminium Powder

Introduction:


As the name would suggest, aluminum powder is simply aluminum in powder form and is created using flakes of aluminum. Aluminum powder is a light, silvery-white to gray, odourless powder. It is a reactive flammable material.

Aluminium powders is used for several applications such as manufacture of slurry, explosive and detonators, thermit process used for manufacture of ferro alloys and for specialised welding applications such as rails, pyrotechnic to manufacture crackers, sparkles and other pyrotechnic products; manufacture of aluminium paste, paints and several powder components used in automobiles. And it is also used in the production of different types of electronics. In addition to those uses, it is found in a lot of different paints and sealants on the market as well.

The most important property of aluminium powder to undergo a vigorous exothermic reaction when it gets oxidised finds application in pyrotechnic process. It is because it’s much safer and easier to handle than its alternatives. In addition to the safety aspect, aluminum powder combined with mixing other compounds can help produce some spectacular and varied effect when used in fireworks. In foundry, aluminium powder is used as a deoxidant and exothermic tapping compounds to increase the yield of casting.

Where to buy aluminum powder? Various aluminum powder are sold at AEM. If you did not find the powders you need, please feel free to contact us. We can supply customized sizes and powders according to your requirements.

Aluminium Metal powder


The aluminium powder is manufactured in several forms such as flake-like particles, granular powder (atomised aluminium) etc. Aluminum powders are used in paints, pigments, protective coatings, printing inks, rocket fuel, explosives, abrasives and ceramics; production of inorganic and organic aluminum chemicals; and as catalysts. aluminium powder is mixed with carbon and used in the manufacture of fireworks. The coarse powder is used in aluminothermics (thermite reaction).

Aluminium Oxide Powder


Aluminium oxide is an amphoteric oxide of aluminium with the chemical formula Al2O3. It is also commonly referred to as alumina, corundum, sapphire, ruby or aloxite in the mining, ceramic and materials science communities. It is produced by the Bayer process from bauxite. We are reckoned as one of the preeminent Aluminum Oxide Powder suppliers from China. The array of the Aluminum Oxide Powder includes High Temperature Aluminum Oxide Powder and Low Sodium Aluminum Oxide Powder meeting the specific requisites of the applications. The Aluminum Oxide Powder offered by us are used in many specialty markets that include precision optics, electronics, semi-conductor, micro blasting, heat sink compounds, ceramic, metal lapping, wear-resistant surface coatings.
