7 Series aluminum alloys overview
7 series aluminum alloys are aluminum-magnesium-zinc-copper alloys, mainly zinc, but sometimes magnesium and copper are also added in small amounts. Among them, super hard aluminum alloy is the alloy containing zinc, lead, magnesium and copper, which is close to the hardness of steel.
7xxx series aluminum alloys are heat treatable alloys, which are super hard aluminum alloys with good wear resistance, slower extrusion speed than 6 series alloys, and good welding performance.
7000 series aluminum alloys also belong to aviation series, application scope: aviation (aircraft load-bearing components, landing gear), rocket, propeller, airship.
Hot selling 7 series aluminum sheet -7075
The representative of 7 series aluminum sheet 7075 , mainly contains zinc elements.
7075 aluminum sheet is stress relieved, will not be deformed and warped after processing. 7075 aluminum sheet has high thermal conductivity, which can shorten the molding time and improve work efficiency.
7075 is mainly characterized by high hardness, is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures and other high stress structural parts requiring high strength, corrosion resistance, mold manufacturing.
