The "See also" section has one entry, to Northwest Airlines Flight 421, which makes no mention of aluminum 7075, nor any alloy. Perhaps there was some connection in a past version of that page, but there seems no reason for the link currently. 173.180.151.52 20:34, 23 February 2018 (UTC) anon
Another application for the 7075-series alloy has been in connecting rods used in drag racing engines. Aluminum rods do not have the fatigue life of forged steel rods, but have less mass than their steel counterparts, resulting in lower mechanical stress during periods in which an engine is operated under full-throttle, high-RPM conditions.
7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
Many metals and thermoplastics can be welded, but some are easier to weld than others (see Rheological weldability). A material's weldability is used to determine the welding process and to compare the final weld quality to other materials. Weldability is often hard to define quantitatively, so most standards define it qualitatively.

Consisting of alloys that were meant to replace the popular 2024 and 7075 alloys directly, the second generation of Al–Li had high lithium content of at least 2%; this characteristic produced a large reduction in density but resulted in some negative effects, particularly in fracture toughness. The third generation is the current generation ...
In welding, equivalent carbon content (C.E) is used to understand how the different alloying elements affect hardness of the steel being welded. This is then directly related to hydrogen-induced cold cracking, which is the most common weld defect for steel, thus it is most commonly used to determine weldability.
