Summary of tensile strength values for various wrought aluminum materials. The ranges of the tensile strength values obtained by varying the composition are trended from left to right. The vertical change bar shows how much the strength of alloys with the same chemical composition can be affected simply by manipulating the microstructure through adequate processing. This trend example could be of particular interest for future designs of scrap-tolerant alloy variants and the underlying process and heat treatment variants.596 The wrought aluminum alloy groups indicated above the bars follow the standard description, indicating the main alloying element(s) in aluminum alloys: 1xxx, close to commercially pure aluminum; 2xxx, copper; 3xxx, manganese; 4xxx, silicon; 5xxx, magnesium; 6xxx, magnesium and silicon; 7xxx, zinc, copper and magnesium.
