View source for René 41

{{Short description|Nickel-based high temperature, high strength alloy}}'''René 41''' is a [[nickel]]-based high temperature [[alloy]] developed by [[General Electric]]. It retains high strength in the {{convert|1200-1800|F|C|-2|order=flip}}  temperature range. It is used in jet engine and missile components, and other applications that require high strength at extreme temperatures. René 41 is considered a nickel alloy based upon its chemical composition.<ref>{{cite web|title=Rene 41 Chemistry|url=http://www.rolledalloys.com/alloys/cobalt-alloys/rene-41/en/|work=Rolled Alloys Inc.|accessdate=October 29, 2014|archive-date=February 15, 2017|archive-url=https://web.archive.org/web/20170215212651/https://www.rolledalloys.com/alloys/cobalt-alloys/rene-41/en/|url-status=dead}}</ref>
