2A06 aluminum bar rod

The 2A06 aluminum bar is a typical hard aluminum alloy in the aluminum-copper-magnesium system, and its composition is reasonable and the comprehensive performance is good. This alloy is produced in many countries and is the largest used in hard aluminum. The alloy is characterized by high strength and a certain heat resistance, and can be used as a working part below 150 °C. The temperature is higher than 125 ° C, and the strength of the 2a06 alloy is higher than that of the 7075 alloy. The forming properties are better in the hot state, annealing and new quenching conditions, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. The corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; it is easy to crack when welding, but it can be welded by special process.


 
2A06 aluminum bar is high-strength hard aluminum, the pressure processing performance and machinability are the same as 2A12, and the plasticity is good under annealing and quenching conditions. 2A06 aluminum alloy can be quenched and aged. The general corrosion stability is the same as that of 2A12. When heated to 150-250 °C, the tendency to form intergranular corrosion is smaller than that of 2A12. The spot weldability is the same as that of 2A12 and 2A16. Argon arc welding Better than 2A12, but worse than 2A16.
Due to its high strength and good fatigue strength, 2A06 aluminum alloy rods are widely used in aircraft structures, rivets, truck hubs, propeller components and other structural components, especially under tension between the wing and fuselage structure.
