Description of Aluminum Alloy 7050 (UNS A97050) Plate/Sheet
Aluminum alloy 7050 has high strength, and strong corrosion resistance. Moreover, it is a low-temperature alloy with good strength increase. Aluminum alloy 7050 is an aluminum alloy with zinc as a primary alloying element, making it has the ability to stay strong over time. Due to its high strength, low density, thermal properties and its ability to be highly polished, 7050 is widely used in mold tool manufacture. The aluminum 7050 plate/sheet is a top choice for use in aerospace applications.
