Hi Barry. You can check the thread pitch. If it's 26tpi then it's likely of Italian origin. Or at least intended as a replacement for an Italian axle, e.g. Campy. If it's 1.0mm [25.4tpi] then it's more likely of Asian or non-Italian European origin [or intention]. If you don't have a gauge you can use the threads of an axle of known pitch to check. Axles don't rotate so it seems a bit silly to make them of anything other than steel. Cheers. Billy Ketchum; Chicago, IL; USA.
I am curious about this too. I have a ti axle on my desk that I am not sure of who the maker was .
On a soilmilar note, i have some aluminum axles - who would have made these? cobra? Do they make sense, theyre so light,
