2024 aluminum rod for the typical hard-Al - Cu - Mg alloy, its composition is more reasonable, American Airlines 2024 aluminum rod (4) overall performance is better.Many countries are producing this alloy, is the largest amount of hard aluminum. The alloy is characterized by: high strength, heat resistance and can be used as the working parts below 150 ℃. Temperature higher than 125 ° C, the strength of the 2024 alloy is higher than the 7075 alloy. Forming performance under thermal conditions, annealing and quenching state is better than the heat treatment to strengthen the effect is remarkable, but the heat treatment process is demanding. The poor corrosion resistance, but with aluminum coating can be effectively protected; welding cracks easily, but using a special process welding, can also be riveting. Hard aluminum is a high strength 2024 aluminum rod can be heat treated to strengthen plastic state quenching and just quenching medium, spot welding using gas welding when there is a tendency to the formation of intergranular cracks, alloy after quenching and cold hardening The cutting performance is still good, after annealing can be cut low: high corrosion resistance, often anodized and painted or surface-coated aluminum layer in order to improve its corrosion resistance.2024 is mainly used for the production of high load of parts and components (but not including stampings forgings), such as below 150 ℃ in the skeleton parts in the aircraft skin, bulkheads, wing ribs, wing spars, rivets and other parts.
