2A06 aluminum square bar/round bar manufacturer china suppli

2A06 aluminum square bar/round bar  is a typical hard aluminium alloy in the aluminium-copper-magnesium system. Its composition is reasonable and its comprehensive performance is good. Many countries produce this alloy, which is the largest amount of hard aluminium. The alloy is characterized by high strength and heat resistance, and can be used as working parts below 150 degree C. The strength of 2A06 alloy is higher than that of 7075 alloy when the temperature is higher than 125 degree C. The formability is better in hot state, annealing and new quenching state, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. Corrosion resistance is poor, but pure aluminium coating can be effectively protected. Cracks are easy to occur during welding, but special technology can be used to weld.
 
2A06 aluminum square bar/round bar is high strength hard aluminium. Its machinability and machinability are the same as those of 2112. Its plasticity is good under annealing and hardening conditions. 2A06 aluminium alloy can be quenched and aged. Generally, the corrosion stability is the same as that of 2A12. When heated to 150-250 C, the tendency of intergranular corrosion is smaller than that of 2A12. Spot weldability is the same as that of 2A12 and 2A16. Argon arc welding is better than that of 2A12, but worse than that of 2A16.
 
 
2A06 aluminum square bar/round bar application ：
 
Because of its high strength and good fatigue strength, 2A06 aluminium alloy bars are widely used in aircraft structures, rivets, truck hub, propeller components and other structural components, especially where tension occurs in wing and fuselage structures.
