The difference between the state of aluminum alloy and aluminum plate is that under normal circumstances, the internal stress of will be relatively large and the processing will deform. The most suitable state for processing should be that it is the main alloy of aluminum alloy that is stretched on the basis of to eliminate the internal stress. The elements are magnesium and silicon and form phases. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron. Sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly 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 grains and control the recrystallized structure. In order to improve the machinability, lead and bismuth can be added. When solid dissolved in aluminum, the alloy has artificial age hardening properties. The main alloying elements in aluminum alloys are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect.
Alcoa has excellent processing performance, good corrosion resistance, high toughness, no deformation after processing, easy color coating, and excellent oxidation effect.
Medium alloy, medium strength, good plasticity and excellent corrosion resistance. In particular, it has no tendency to stress corrosion cracking, has excellent weldability, corrosion resistance and cold workability, making it a promising alloy with a wide range of applications. It can be anodized and colored, or painted with enamel, and is suitable for use as building decoration materials. It contains a small amount, so its strength is higher than that of steel, but its quenching sensitivity is also relatively high. Wind quenching cannot be achieved after extrusion, and it requires re-solution treatment and quenching aging to obtain higher strength.
