The outstanding chemical property of 3003 aluminum sheet is about the corrosion resistance, while the physical property is about the high strength. Because 3003 aluminum alloy has high strength and corrosion resistance, it is widely used in the field of aluminum tread plate, packaging foil, container foil and aluminum-plastic composite board. At present, the production of 3003 aluminum sheet plate generally adopts the casting + cold rolling production process, because the production process period of casting + cold rolling is short, the equipment investment is low and the energy consumption is low.
3003 aluminum sheet has good corrosion resistance in 3000 series aluminum, which close to the corrosion resistance of industrial pure aluminum, aluminium sheet 3003 has good corrosion resistance to the atmosphere, fresh water, seawater, food, organic acids, gasoline, neutral inorganic salt solution, etc. The corrosion resistance in dilute acid is also very good. In the cold deformation state, 3003 aluminum alloy has the tendency of exfoliation corrosion, and the greater the deformation, the more severe the exfoliation. Anodization is generally not performed because of the uneven color after anodization. According to the chemical properties of 3003 aluminum sheet, it has wide application in the places which need good corrosion resistance, combine with the good physical properties, 3003 aluminum sheet has been one of the most widely used aluminum sheet plate in the 8 series aluminum alloys.
