What's the difference between 606 1 aluminum plate and 5052 aluminum plate?

The difference between the state t6 of 606 1 aluminum plate and t65 1 aluminum plate is that, under normal circumstances, the internal stress of t6 will be relatively large, and the processing will be deformed. The most suitable treatment state should be t65 1, stretching on the basis of t6. The main alloying elements of 606 1 aluminum alloy are magnesium and silicon, forming mg2si phase. If it contains a certain amount of manganese and chromium, it can neutralize the adverse effects of iron; Sometimes a small amount of copper or zinc is added to improve the strength of the alloy without obviously reducing its corrosion resistance; There is also a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on conductivity; Zirconium or titanium can refine the grain and control the recrystallization structure; In order to improve machinability, lead and bismuth can be added. When mg2si is dissolved in aluminum, the alloy has the effect of artificial age hardening. The main alloying elements in 606 1 aluminum alloy are magnesium and silicon, which have moderate strength, good corrosion resistance and weldability, and good oxidation effect.

Alcoa 606 1 has excellent processability, good corrosion resistance, high toughness, no deformation after processing, easy coloring and film formation, and excellent oxidation effect.

It's aluminum magnesium antirust aluminum. Compared with 3a2 1, 5052 has higher strength, especially higher fatigue strength. Similar to 3a2 1, it has high plasticity and corrosion resistance; The heat treatment can not be strengthened, the weldability of contact welding and hydrogen atom welding is good, and there is a tendency of crystal crack during argon arc welding; The alloy has good machinability in cold work hardening and semi-cold work hardening state, but poor machinability in annealing state and can be polished.
