7A33 O T6 T62 Aluminum alloy sheet plate

7A33 O T6 T62 aluminum alloy sheet plate is Al-Mn-Mg can be strengthened by heat treatment of high corrosion resistance of mild structure Aluminum Alloy, have high resistance to seawater and marine atmospheric corrosion, no intergranular corrosion, stress corrosion and exfoliation corrosion tendency and strength of 2A12 alloy is also good fracture toughness, technology of plastic and low notch sensitivity. Electric welding and seam, skin and structures suitable for use in coastal areas and shipboard aircraft, helicopters, aircraft manufacturing water, can replace the 2A12 alloy.
7A33 alloy is mainly semi-finished sheet, aluminum clad 7A01 alloy
