2024 T4 aluminum sheet is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is reasonable and its comprehensive performance is good. Many countries produce this alloy, which is the largest amount of duralumin. The characteristics of the alloy are: high strength, a certain heat resistance, can be used as working parts below 150 ℃. 2024 aluminum alloy with a density of 2.85 g/cm3.
The strength of 2024 alloy is higher than that of 7075 alloy. The formability is better in hot state, annealing and new quenching state, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. The corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; cracks are easy to occur during welding, but it can be welded or riveted by a special process.
2024 aluminum sheet is widely used in aircraft structures (skins, skeletons, ribs, bulkheads, etc.), rivets, missile components, truck wheels, propeller elements and various other structural parts.
