2024 for magnesium aluminum - copper - is typical of hard aluminum alloy, its composition is reasonable, comprehensive performance is better. Many countries are the alloy production, is the largest in the dural dosage. The characteristics of the alloy are: high strength, heat resistance to a certain extent, can be used as a working parts below 150 ° C. Temperature higher than 125 ° C, the strength of 2024 alloy is higher than that of 7075 alloy. Thermal state, annealing and quenching conditions forming performance are good, heat treatment reinforcement effect is remarkable, but strict heat treatment process. Poor resistance to corrosion, but with pure aluminum coating can be effectively protected; During welding are prone to crack, but the use of special process can welding, can also be riveted. Widely used in aircraft structure, rivets, truck wheel, screw elements, and other various structures.
2024 aluminum alloy with high strength and good fatigue strength, are widely used
