2A12 Aluminum Bar is a high-strength duralumin alloy in the Al-Cu-Mg system with a well-balanced composition and excellent overall performance. It is widely used in aerospace and military applications due to its superior mechanical properties. The alloy offers high strength, good fatigue resistance, and certain heat resistance, making it suitable for structural components operating below 150℃. Compared with other high-strength aluminum alloys, 2A12 maintains excellent formability in the hot, annealed, and newly quenched conditions. Its corrosion resistance is relatively low but can be effectively improved with protective coatings. Special welding or riveting techniques are required due to its susceptibility to cracking.
Applications:
2A12 aluminum bars are commonly used in aircraft structural components, rivets, missile parts, truck wheels, propeller shafts, and other high-strength structural parts.
