Aluminum alloy 2000 series
grade 2xxx grades of this type of aluminum plate/ tube/ rod (2011, 2014, 2017, 2018, 2124, 2219, 2319, 201.0; 203.0; 206.0; 224.0; 242.0; Others require hot baking process to get the highest specification. In this process, Mechanical properties are similar. Or perhaps higher than that of low carbon steel. And in some cases, repeated heat treatment. It can increase mechanical properties. This heat treatment will increase the rooting point. This will damage the elongation. This will make the tensile strength is not good.
