Elongation of 3003 aluminum circle
3003 aluminum circle is among the most frequently applied aluminum circle discs in cookware and lamps. Containing an alloying metal of manganese, the circle has an outstanding corrosion resistance, especially in comparison to 1050, 1060, 1070 and 1100 circles. In addition to corrosion resisting ability, elongation serves as an important factor influencing the manufacturing process and application conditions of 3003 aluminium circle as well. Among leading 3003 aluminum circle manufacturers in China, we would like to share the elongation of the circle sheet under different tempers and process states here.

We can see that the harder the 3003 aluminum circle, the bigger its elongation. When the other conditions are the same, the smaller the crystal grains, the larger the elongation. However, if the difference in process parameters is different due to the difference in process parameters, and the work hardening state is different, then the grain size cannot be used to judge the elongation. Take the following case for example.
Sample 1 has a low heat distortion temperature, less recrystallization, a large number of dislocations, and a large internal stress. Although the crystal grains are fine but the plasticity is poor.
Sample 2 has a higher heat distortion temperature, a higher number of crystals, a lower number of dislocations, and a smaller internal stress. Although the crystal grains are larger, the plasticity is good.
