The body structure of an airplane usually consists of wings, fuselage, tail and landing gear. If the aircraft's engine is not in the fuselage, the engine compartment is also part of the body structure. Generally, the front part of the aircraft contains the crew and many avionics; The middle section of the aircraft includes wings, fuel tanks and weapons equipment. Today I'd like to share with you the aviation aluminum 2024Development in aircraft manufacturing
2024 is a typical hard aluminum alloy in aluminum-copper-magnesium series, with reasonable composition and good comprehensive performance. Many countries produce this alloy, which is used in hard aluminum. The characteristics of the alloy are: high strength, heat resistance to a certain extent, can be used as a working parts below 150 ° C. Temperature higher than 125 ° C.
The strength of the 2024 alloy is higher than that of the 7075 alloy. The forming performance is good under the hot condition, annealing and new quenching condition, and the heat treatment strengthening effect is obvious, but the heat treatment technology is strict. The corrosion resistance is poor, but it can be effectively protected by pure aluminum coating. Cracks are easy to occur in welding, but special techniques can be used for welding or riveting. Widely used in aircraft structures, rivets, truck wheels, propeller components and other structural parts.
Because of its high strength and fatigue strength, 2024 aluminum alloy has been widely used in aircraft structures (cover, frame, rib, spacer, etc.), rivets, missile structures, propeller components and other structures.
