brine f seiries shafts

[SBAatk22]

I know that brine no longer makes these shafts but i have a f22 and f15 and have no clue what kind of metal both are. here are some of my guesses of what all the shafts are.

f 10 - aluminum

f 15 - titanium??

f 22 - no idea?

f 55 - no idea?

if you know what mtelas these shafts are please tell. they seem to be very nice. my f22 is 2 years old and no dents and my f15 is 4 years old and no dents. so please tell me what metals these are. thanks

F-15 is aluminum enhanced with some titanium in the mixture.

Look at the thread I linked for exact aluminum composition.
