Where is it applied?

1. Mining industry. Aluminum powders as high-energy additives are included in many industrial explosives used in the mining industry - ammonals, rock ammonites, detonites, alumotol. This significantly increases the heat of explosive transformation of explosives and indicators of their performance;
2. Ferrous metallurgy. In ferrous metallurgy, aluminum powders (granules) are used as a reducing agent. The addition of 0.1-1.5% aluminum grains to molten iron completely frees it from oxide and thus provides a dense casting without cavities. Aluminum powders are used to heat the top part of the ingot when casting ferrous metals. A mixture of oxides and aluminum powders is stuffed around the sprue hole and the profit, which “ignites” from the melt and, while burning, maintains the cast metal in a liquid state for a long time. This makes it possible, when the casting is solidified and the volume of metal is reduced, to add the mold and thereby avoid the formation of shrinkage cavities in the castings. In the production of ferroalloys, aluminothermic reduction of oxides of refractory metals is widely used. In this way, ferromolybdenum, ferroniobium, ferrotungsten, etc. are obtained, while powders with a particle size of 5 to 300 microns are usually used. Thermite mixtures Fe ₂ O ₃ - Al have gained worldwide distribution. A stoichiometric mixture of 75% Fe ₂ O ₃ + 25% Al gives a combustion temperature of about 2500 ° C;
3. Chemical industry. In the chemical industry, aluminum powders and granules are successfully used for reducing purposes, since they quickly react in aqueous acidic or alkaline media with the release of hydrogen, which at the time of formation is one of the strongest reducing agents: 1 kg of aluminum powders gives 1240 liters of hydrogen. Aluminum powders are widely used in the production of aluminum alkyls, in the polymerization of ethyls, in the production of antiknock tetraethyl lead, etc.;
4. Obtaining aluminum coatings on metals. Aluminum powders are used for coating, mainly on steel products. Spray metallization, plasma spraying and powder metallurgy (powder rolling on the surface of a steel sheet with subsequent heat treatment) have received the greatest application;
5. In the composition of rubber in the manufacture of car tires in order to increase the thermal conductivity of the tread rubber and improve the working conditions of the inner surface of the tires. The addition of powders to plastics improves their mechanical properties, increases their wear resistance, gives them special properties (electrical conductivity, thermal conductivity, etc.);
6. Widely used as a filler in resin-based plastics such as epoxy, polyester and phenolic;
7. For the preparation of so-called "cold solders" (putties), which are used to fill sinks, potholes, cracks and seams on the metal surface;
8. In the production of high-density refractory materials (the addition of aluminum powders makes it possible to increase the density, heat resistance and mechanical density of refractories);
9. To obtain porous adsorption materials for cryogenic technology;
10. In the production of welding flux-cored wire;
11. For obtaining lubricating-cooling liquids (coolant).
