Aluminum 7050

Aluminum 7050 (UNS A97050) is an aluminum alloy comprised of mostly aluminum (Al), zinc (Z), and copper (Cu). Trace amounts of other elements such as magnesium (Mg), chromium (Cr), Zinc (Z), titanium (Ti), and others make up the rest of this alloy.

Aluminum 7050 is a high-strength, yet lightweight aluminum alloy that is commonly used in the aerospace industry for various structural components. It also has high corrosive resistance characteristics for aluminum alloys and overall has high toughness to resist cracking – making it ideal for many structural applications.
