Whats my frame made from.

[1979Andrew]

Is this titanium or aluminium? Ive had ago with some wire wool and it seems to polish up a little. There are some deep scratches though that the wire wool wont touch i wonder if its raw aluminium though?
Its a very light frame and pings when i hit it with an allen key

Looks ti to me too. Got any pictures of the drop outs and any of the tubes so we can see thickness.
