Aluminum 7050 Product Guide
Overview
7050 Aluminum is similar to the other popular 7000 series aluminum alloy 7075, however it is less quench sensitive. This allows the alloy to maintain strength properties over time better than other high strength alloys, especially in thick sections. 7050 T7451 also displays better corrosion resistance, exfoliation resistance, and toughness than standard high strength alloys making it very popular in the aerospace industry where it is used for bulkheads, fuselages, and wing skins.
