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.
The world's first mass-production usage of the 7075 aluminum alloy was for the Mitsubishi A6M Zero fighter. The aircraft was known for its excellent maneuverability which was facilitated by the higher strength of 7075 compared to previous aluminum alloys.

In 2000, the U.S. was the largest producer of primary aluminum. The six remaining smelters in the U.S. now make up a small percentage of global capacity.
It is easily machined in certain tempers, and among the strongest available aluminium alloys, as well as having high hardness. However, it is difficult to weld, as it is subject to cracking. [2] 2014 is the second most popular of the 2000-series aluminium alloys, after 2024 aluminium alloy. It is commonly extruded and forged.
As recently as 1981, the US produced 30% of the world's primary aluminum, and for many years up through 2000, the US was the world's largest producer of primary aluminum. In 2014, by contrast, the US ranked sixth in primary aluminum production, and provided only 3.5% of world production.
