More about 2024 aluminum plate

The 2024 aluminum plate is a typical hard aluminum alloy in the aluminum-copper-magnesium system, and its composition is reasonable and the comprehensive performance is good. This alloy is produced in many countries and is the most used in hard aluminum. The alloy is characterized by high strength and a certain heat resistance, and can be used as a working part below 150 °C. 2024 aluminum alloy, density is 2.85 g/cm3.


The 2024 alloy grade was registered by the United States in 1954. The temperature is higher than 125 ° C, and the strength of the 2024 alloy is higher than that of the 7075 alloy. The forming properties are better in the hot state, annealing and new quenching conditions, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. Corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; it is easy to crack when welding, but it can be welded or riveted by special process. Widely used in aircraft structures, rivets, truck hubs, propeller components and other structural components.
