Refers to small particles of attraction. aluminium powder can be divided into industrial aluminium powder according to its use, which is prepared by atomization method or centrifugal atomization method and used in metallurgical industry and chemical industry; Coatings: aluminium powder, prepared by ball milling method, used in anti-corrosion, decoration and chemical industry; Gas generating aluminium powder, prepared by ball milling method, used in construction, pesticide and chemical products; Flammable aluminium powder, prepared by atomization method, phase pyrotechnic, chemical catalyst and electrode products; Flammable fine aluminum powder, prepared by atomization method or atomization plus ball milling method, used for explosive and pesticide products. The gas atomization powder is spherical, and the water atomization powder is irregular in shape. The centrifugal method has quasi spherical, needle shaped and short fiber dimensional shapes, and the ball milling method is flaky. Ultrafine spherical powder is prepared by vapor deposition.
