Searching "Flexon" on Wikipedia redirects to Nitinol. This article claims its the same stuff, just a specific alloy: https://www.pressrelease.com/news/myeyewear2go-com-eyeglass-frames-with-flexon-for-durability-and-style-19583439 https://www.pressrelease.com/news/myeyewear2go-com-eyeglass-... The Beta Group, who claims to have started Flexon, says "Beta advanced the technology of Nitinol with its pioneering Flexon Ophthalmic Eyewear." https://www.betagroupllc.com/wrought-nitinol/ https://www.betagroupllc.com/wrought-nitinol/ Sounds pretty legit to me unless I see something else saying otherwise. I think they just stress the titanium of it as a lot of consumers probably think of titanium as a "space age" futuristic metal that they make space ships and the SR-71 and Lt. Dan's legs out of. Saying its made of Nitinol means nothing to a lot of average consumers.
