- 2018-03-10 16:43 -
Zn is the main alloying element of 7000 series aluminum alloy, something will added a small quantity of Mg and Cu. 7005 aluminum alloy and 7075 aluminum alloy are the high end product of 7000 series aluminum alloy, they can be strengthened by heat treatment.
 aluminum sheet price
7000 series aluminum alloy has a wide range of application in aerospace (like bearing members, landing gear), rockets, propellers, etc.
7005 aluminum sheet is widely used for the welding structures that require a high strength and a high fracture toughness, such as large heat exchangers, the trusses, rods, containers for transport vehicles, it also used for sports equipment like tennis rackets and softball bats, etc.
7039 aluminum sheet is widely used for refrigerated containers, cryogenic equipment and storage tanks, pressure equipment of fire protection, military equipment, armor plates, missile devices, etc.
7050 aluminum sheet is widely used in the plates, extrusions, forgings and die forgings of aircraft structure, this structures has a  high requirement in anti-stripping corrosion, stress corrosion cracking, fracture toughness and fatigue resistance.
7475 aluminum sheet is widely used for the plates, wing frames, purlins, etc. of aircraft, it also can be used for some parts that require a high strength and a high fracture toughness.
7a04 aluminum sheet is widely used for aircraft skin, screws, and load bearing members like beam girders, bulkheads, ribs, landing gear, etc.
