2024 T351 aluminum bar is a typical hard aluminum alloy in the aluminum-copper-magnesium series, with reasonable composition and good overall performance. Many countries produce this alloy, which is the largest in duralumin. The characteristics of the alloy are: high strength, a certain degree of heat resistance, and can be used as working parts below 150°C. At temperatures higher than 125°C, the strength of
2024 alloy is higher than that of
7075 alloy. The heat treatment, annealing and new quenching conditions are relatively good in formability, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by covering with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by special technology.
The alloy element of
2024 T351 aluminum bar is copper, which is called duralumin, which has high strength and good cutting performance, but its corrosion resistance is poor. It is widely used in aircraft structures (skins, skeletons, rib beams, bulkheads, etc.), rivets, missile components, truck hubs, propeller components and various other structural parts. It is Al-Cu-Mg series.
