Aluminum is one of the most abundant metals found in the Earth’s crust. It accounts for nearly 8% (by weight) of the Earth’s crust. Aluminum is the most widely used mental across the globe due to its wide availability and numerous properties. Aluminum powder is manufactured by feeding pure molten aluminum metal to a compressed gas jet and converting it to fine droplets. These droplets are solidified and collected. Powders collected through this process are graded, depending on their size and specification for various application. Aluminum powder is extensively used in a wide variety of applications such as aerospace & defense, industrial, automotive, and construction. Aluminum flakes and flake pigments are produced by dry ball milling of atomized aluminum under inert atmosphere or removal of solvent from wet-milled atomized aluminum under controlled conditions. Aluminum paste is made by ball milling of aluminum foil or aluminum powder in white solvents in the presence of a lubricant. Aluminum paste is extensively used by anti-corrosion paints, roof coatings, printing inks. Aluminum powder, paste & flakes are widely used in automotive paints & coatings. These are emp...
