What kind of material is 2A12 aluminum sheet?
Corrosion resistance is poor, but it can be effectively protected by pure aluminum coating. 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 many other structures.
The temperature is higher than 125 degrees C, and the strength of the 2024 alloy is higher than that of the 7075 alloy. Under the condition of hot state, annealing and new quenching, the formability is better, and the strengthening effect of heat treatment is remarkable, but the heat treatment process is strict.
2A12 is a typical Al Mg alloy in Al Cu mg system. Its composition is reasonable and its comprehensive properties are better. Many countries produce this alloy, which is the largest in use. The alloy is characterized by high strength, a certain heat resistance, and can be used as working parts below 150 degrees C.
