What are the 7 series aluminium alloy sheets?

7005 Extruded material, used in the manufacture of welded structures that require both high strength and high fracture toughness, such as trusses, rods and vessels for transport vehicles; large heat exchangers, and components that cannot be solidified after welding; also used in the manufacture of sports equipment such as tennis rackets and softball bats.

7039 Refrigerated containers, cryogenic instruments and storage tanks, fire-fighting pressure equipment, military equipment, armour plates, missile devices.

7049 is also one of the 7 series aluminium alloy sheets, and it is used for forging parts with the same static strength as 7079-T6 alloy but requiring high resistance to stress corrosion cracking, such as aircraft and missile parts - landing gear hydraulic cylinders and extrusions. Parts with fatigue properties roughly equal to those of alloy 7075-T6, but with slightly higher toughness.

7050 aircraft structural parts with medium thick plates, extrusions, free forgings and die forgings. The requirements for the manufacture of such parts are: resistance to spalling corrosion, stress corrosion cracking capacity, fracture toughness and fatigue resistance are high.

7072 Aluminium foil and extra-thin strips for air conditioners; cladding for 2219, 3003, 3004, 5050, 5052, 5154, 6061, 7075, 7475, 7178 alloy sheets and tubes.

7075 as the 7 series aluminium alloy sheets for the manufacture of aircraft structures and futures other highly stressed structural parts requiring high strength and corrosion resistance, mould making

7175 for forging high-strength structural for aircraft. t736 materials have good all-round properties, i.e. high strength, resistance to spalling corrosion and stress corrosion cracking, fracture toughness, fatigue strength.

7178 Parts for the manufacture of aerospace vehicles requiring high compressive yield strength.

7475 Aluminium-clad and unclad sheets for fuselages, wing skeletons, trusses, etc. Other parts requiring both high strength and high fracture toughness.

7A04 7 series aluminium alloy sheets can be used for aircraft skins, screws, and stressed elements such as beam trusses, spacers, wing ribs, landing gear, etc.
