One of my road bikes from the 70's has titanium bottom bracket bolts, but I didn't know that until the first time I took it apart.? Titanium was unusual back then, and I had never actually held a piece.? My first thought was "aluminum!?", but a quick check of some catalogs revealed the truth.? I remember holding them for hours- it was hard for me to accept that bolts that light weight could actually be strong.

Thanks everyone for the very detailed replies and discussion - fascinating.
I found out myself yesterday why bolts aren¡¯t made from aluminium. I might as well have been trying to put a thread on a bar of chocolate. It was not a success. Oh well, you live and learn¡
