The use of aluminum Aluminum used in aerospace is used to manufacture aircraft skins, fuselage frames, beams, rotors, propellers, letter boxes, side plates and landing gear struts, as well as rocket forging rings and spacecraft side plates. It is widely used in the packaging of beverages, food, cosmetics, medicines, cigarettes, industrial products, etc. Aluminum materials for transportation can provide various aluminum alloy materials for automobiles, large porous profiles for subways and light rails, which fill the gap in China. Meet the localization requirements of subways, and can be used to manufacture automobiles, subway vehicles, railway passenger cars and high-speed passenger car body structures. Parts, doors, windows and shelves, automobile engine parts, air conditioners, radiators, body panels, wheels and ship materials. All aluminum cans for packaging are a sign of the level of aluminum processing. Aluminum is mainly used as metal packaging material in the form of sheet and aluminum foil to make cans, lids, bottles, barrels and packaging aluminum foil. The aluminum printing industry for printing has bid farewell to "lead and fire" and entered the era of "light and electricity"... Aluminum-based PS boards provide strong support for this transformation of the printing industry. Aluminum materials for electronic appliances are mainly used in various busbars, wiring, conductors, electrical components, refrigerators, cables and other fields. Air conditioner aluminum foil has good deep drawing performance, high strength and good ductility, reaching the level of similar imported products; high-performance electrolytic capacitor foil fills the domestic gap. Because of its good corrosion resistance, sufficient strength, excellent processing performance and welding performance, aluminum alloy for architectural decoration is widely used in building frames, doors and windows, ceilings, decorative surfaces, etc.
