1. Introduction à la 2024 materials
2024 is a typical hard aluminum alloy in the aluminum-copper-magnesium system, with relatively reasonable composition and good overall performance. Many countries produce this alloy, which is the largest amount of hard aluminum. The alloy is characterized by high strength and certain heat resistance, and can be used as working parts below 150°C. The temperature is higher than 125°C, and the strength of the 2024 alloy is higher than that of the 7075 alloy.
The forming performance is relatively good in the thermal state, annealing and new quenching state, and the heat treatment strengthening effect is significant, but the heat treatment process requires strict requirements. It has poor corrosion resistance, but it can be effectively protected by cladding with pure aluminum; cracks are prone to occur during welding, but special processes can be used to weld or rivet. Widely used in aircraft structures, rivets, truck hubs, propeller elements and various other structural parts.
