New magnesium-zinc aluminum alloy bodies and methods of producing the same are disclosed. The new magnesium-zinc aluminum alloy bodies generally include 3.0-6.0 wt. % magnesium and 2.5-5.0 wt. % zinc, where at least one of the magnesium and the zinc is the predominate alloying element of the aluminum alloy bodies other than aluminum, and wherein (wt. % Mg)/(wt. % Zn) is from 0.6 to 2.40, and may be produced by preparing the aluminum alloy body for post-solutionizing cold work, cold working by at least 25%, and then thermally treating. The new magnesium-zinc aluminum alloy bodies may realize improved strength and other properties.

One embodiment described herein is a sheet of materialformed into accurate and high value structures by implementing a plurality of elongated slotsthat are obliquely placed along a fold linewhich create one or more stripsconsisting of a length w, a width s and an angle f to said fold line. The stripsare put into a state of plastic deformation through torsion which is controlled via the combination of said length w, width s, and angle f elements to create accurate, unique, complex and high value products or forms. The embodiments described allow for a greater degree of freedom of sheet material types, a greater degree of sheet material thicknesses, while simplifying implementation. This and other embodiments are also enclosed.
