I tried to do a search on this, but have you guys typed 'x-metal' in the search of this site? I might as well type in the word 'Oakley' and try to find what I'm looking for!
Any way what I know- X-metal is a titanium alloy composed of 25 different types of metal. X-metal has an incredibly high strength to weight ratio. X-metal is hypoallergenic (because it's titanium). X-metal sunglasses are designed so that parts of the frame flex and parts remain rigid by manipulating the relative thickness and thinness of certain parts of said frame.
What I want to know - what specifically is in x-metal? What is the strength to weight ratio? Is it stronger than standard titanium? Is it stronger than steel? Is x-metal lighter than titanium? And last thing I would like to know is anything else at all you might know.
Here are some videos on x-metal that are pretty interesting.
