Aluminum Alloy Extrusions 7.8Zn - 2.6Mg - 2.0Cuu - 0.10Zr (7068-T6511) Solution Heat Treated, Stress Relieved, and Precipitation Heat Treated
This specification covers an aluminum alloy in the form of extruded bars, rods, shapes (profiles), and tubing.<p>These extrusions have been used typically for structural parts requiring a combination of high tensile strength and moderate fatigue strength, but usage is not limited to such applications.<p>Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; SAE ARP 823 recommends practices to minimize such conditions.
