They don't call it Titanium for nothing. Ti at ANY diameter will be stronger
than steel. The fact that they make submarine hulls out of the stuff is a
dead give away. Or better yet, the wing skeleton of a 747 is made from Ti
tubing. You can pick up a 50 ft section with a 8 inch diameter and wall
thickness 1.5mm, drop it from over your head: It won't even ding. Try do that
with any steel alloy of the same configurations any day of the week. Cheers,
