You guys need to admit you have NFI about materials.
Pure titanium, and grade 5 titanium alloy have vastly different properties. Googling Ti isnt going to help you here lol
You keep reinforcing your opinion which has already been stated.
...but your explanation is still wrong, so get over it.
Titanium has a low coefficeint of Plasticity, compared to steel alloys.
That is what makes it brittle when used in a sheet or tube or tab.
It's streght to WEIGHT ratio is higher, but that does not have anything to do with Plasticity, it's ability to deflect, or be deformed.
Even if you doubled the wall thickness of a titanium headpipe, it would still be more brittle than a SS headpipe.
When thicker, it will take more force before being damaged, but it will not deform, it will crack.
When you keep saying 'stronger' you are just using an adjective that is intangable in trying to desribe a metals' properties.
What you mean to say is that it's AXIAL resistance to deformation is higher than SS.
....but that is EXACTLY what you don't want, is a high resistance to deformation, because that MAKES IT BRITTLE!
That is why the use of Titanium is limited to linear/axial structures when it is thin, and when it used for radial strength, it is usually very thick (like and artificial leg bone).
