Titanium is strong, not as much so as steel, but of course it is much lighter. Cant say Ive heard of it being used that often though even in high rpm screamers
depending upon grade titanium is not weaker than steel... and has a density of around half.
My dad had an engine built 10 or so years ago with titanium rods. Never missed a beat but titanium prices have gone nuts since then! I think back then 8 rods were 2K I really doubt you will get 4 for 1K now....
I have an ali rod on my book shelf, and as said they are HUGE! very light though, they have a service life. Some people refer to them as stretch rods, as they stretch a little at the top of piston travel to reduce the loads applied by reducing the declaration of the piston a little, they are said to have a certain number of 'stretches' and therefore have a service life as said.
