The 7 series aluminum-zinc-magnesium alloy is the first place in the superduraluminium alloy series. It was used to manufacture airplanes, aviation vehicles. If you need to buy 7 series aluminum alloy, please contact us Haomei Aluminum!
First of all, let's take a look at the characteristics of the 7 series aluminum-zinc-magnesium alloy. 7 series aluminum alloy, as a super-duraluminium alloy series, its material contains a large number of other metal elements, and the main alloying elements are zinc, magnesium, copper. The representative grades of 7 series aluminum alloys commonly on the market are 7050 and 7075. Their heat treatment effect is particularly good, is a super strong deformed aluminum alloy plate. After solid melting, the 7 series aluminum alloy has good plasticity and has good mechanical properties, wear resistance and fatigue resistance. However, they also have disadvantages: poor welding performance, tendency to crack stress corrosion, and need to be treated with aluminum or other protection.
Next, let's take a look at the common 7 series aluminum-zinc-magnesium alloy types on the market and their uses!
7075 : Used for aircraft parts, gears and shafts, instrument shafts and gears, mold manufacturing turbines, keys, aircraft, aviation and defense and other high-stress structural parts that require high strength and strong corrosion resistance. We manufacture 7075 aluminum alloy and 7075 aluminum plate. If you need, you can contact us by email!
7005: Extruded materials for the manufacture of welded structures with both high strength and high fracture toughness, such as trusses, members, containers for transportation vehicles; Large heat exchangers, as well as parts that cannot be solidified after welding; It can also be used to manufacture sports equipment such as tennis rackets and softball bats
7039 : Refrigeration vessels, cryogenic equipment and storage boxes, fire pressure equipment, military equipment, armor plates, missile devices
7050 : Medium and thick plates, extruded parts, free forgings and die forgings for aircraft structural parts. The requirements for the manufacture of such parts for alloys are: high resistance to spalling corrosion, stress corrosion cracking ability, fracture toughness and fatigue resistance
7A04: Aircraft skins, screws, and force components such as girder trusses, compartments, wing ribs, landing gear, etc.
