The duralumin alloys are usually 7xxx, 2xxx and 6xxx aluminum alloys. 7075aluminum plate is one of the most commonly used aluminum alloys with the highest strength. The anodizing 7075 aluminum has higher strength.
In the aviation field, it is mainly used to make aircraft skins, fuselage frames, beams, propellers, fuel tanks, wall panels and landing gear struts, as well as streamlined covers, turntables, remote controls and main components of space launch vehicles, and engine devices. It is also widely used in the fastener industry, mainly for the production of various nuts and shear-resistant high-lock nuts.
7050 is a high-strength alloy of Al-Zn-Mg-Cu series, which can be strengthened by heat treatment. The chemical composition of this aluminum alloy is adjusted on the basis of 7075 super-hard aluminum alloy, the content of zinc and copper is increased, zirconium is used instead of chromium to refine the grains, and the content of impurities such as silicon and iron is reduced.
7050 aluminum is mainly used for main load-bearing structural parts with high strength, good fracture toughness, and high resistance to stress corrosion cracking and exfoliation corrosion, such as thick plates, extrusions, free forgings and die forgings for aircraft structures, such as thick plates, extrusions, free forgings and die forgings for aircraft structures, including fuselage frames, partitions, wing beams, landing gear support parts and rivets.
6063 aluminum is widely used in the development of aircraft-related structures, such as fuselages and wings. 6063 aluminum alloy is available in a variety of forms to meet the needs of different applications.
Whether the application involves bicycle parts, military-grade rifles or plastic industrial molds, 6063 alloy is usually selected. Other types of high-stress structural parts, such as gears, fuse parts and bows, are also made of 6063 aluminum alloy.
2024 aluminum alloy has excellent mechanical properties and corrosion resistance, and is widely used in aerospace, automobile manufacturing, shipbuilding and other fields. 2024 has relatively good fatigue resistance, especially in thick plates, making it suitable for most aircraft structures. 2024 t3 and t4 are its main tempers. Welcome to inquire 2024 t3 aluminum sheet price from us.
2014 aluminum is used to manufacture rims that require high strength, high hardness and withstand high loads, such as rims, truck frames and suspension assemblies, rocket booster fuel tanks and structural parts; 2014 coated aluminum can also be produced to improve its corrosion resistance.
