HS93:
Ok I know it is very difficult to do this but when I bought my lathe I got some material with it, anyway decided to start my first job on the Lathe and some of the material that came with it look ideal as i needed brass about 30 + mm in dia  and this stuff was perfect, the brass has a tinge to it and is as hard as hell even with a new tip  it was very hard work hot or cold the chips come off and look like gold and a bit like bronze to turn the finnish is ok I think I will be able to get it better with time and playing with speeds.it came from a scrap bin  :lol: from somwhere that services helicopter engines and fighter get engines .

That will be some sort of bronze Peter, what type can only be guessed at, unless there is a stamp on the end of the bar, PB1, PB2 etc.

With reference to the aircraft industry, it would not have been used for that, the controls of metals and materials going into engines wouldn't have allowed it to be used in parts manufacture, they have too stringent a control over that. Maybe it had been used for jig making or some such other use off the aircraft.

Hard to say but it is bronze the way it machines it looks like alloy bronze (bronze with aluminium)
I bet a used file wont mark it  :( :( :( :(

Titanium?

HS93:
Unfortunatly I think it is to heavey for Titanium, I got two pieces the same size one a known standard brass and this was by far heaveyer I think it must be as Bogs said bronze.
