7 Series Aluminum Classification and Application Field

[China Aluminum Network] 7 series aluminum features:

Zinc is predominant, but magnesium and copper are sometimes added in small quantities. The superhard aluminum alloy contains the hardness of zinc, lead, magnesium and copper alloys close to the steel. The extrusion speed is slower than that of the 6-series alloy and the welding performance is good. The 7005 and 7075 are higher grades in the 7 series and can be heat-treated.

Applications: Aerospace (aeroplane bearing members, landing gear), rockets, propellers, aviation ships.

7005 Extrusion materials for the manufacture of welding structures that require both high strength and high fracture toughness, such as trusses, rods, containers for transport vehicles; large heat exchangers, and cannot be melted after welding Parts can also be used to manufacture sports equipment such as tennis racquets and softball bats 7039 chilled containers, cryogenic equipment and storage tanks, fire pressure equipment, military equipment, armor plates, and missile devices 7049 for forging static strength the same as the 7079-T6 alloy. It also requires high resistance to stress corrosion cracking components, such as aircraft and missile parts - landing gear cylinders and extrusions. The fatigue performance of the part is roughly equal to that of the 7075-T6 alloy, while the toughness is slightly higher for the 7050 aircraft structural parts using plate, extrusion, free forgings, and die forgings. The requirements for the manufacture of such parts for alloys are: resistance to exfoliation corrosion, stress corrosion cracking, fracture toughness, and fatigue resistance are high 7072 aluminum foil and ultra-thin tape; 2219, 3003, 3004, 5050, 5052, 5154, 6061 , 7075, 7475, 7178 alloy plate and pipe cladding 7075 used to manufacture aircraft structures and futures he requires high strength, strong corrosion resistance of high stress structural parts, mold manufacturing 7175 for high strength structural forging aircraft . T736 material has a good comprehensive performance, namely strength, anti-stripping corrosion and stress corrosion cracking resistance, fracture toughness, fatigue strength are high 7178 for the manufacture of aerospace products require high compressive yield strength parts 7475 body package Aluminium and unclad plates, wing frames, purlins, etc. Other components 7A04 Aircraft skin, screws, and force members such as girders, bulkheads, ribs, landing gear, etc., are required for high strength and high fracture toughness.
