There's no such thing as a lower quality Ti, just the wrong grade used. I doubt that 3 Racing used inferior material, but they may have used the wrong material. I still think that the problem is poor design of the screw, or fatigue - look at the failure on the photo, that doesn't look like a good piece of design to me! HTH  |
there are many forms of ti material,

titanium in its raw form is softer than alloy, by mixing other materials then its strength is achived.
tir use grade 5, for mclarens and rc applications.
im told 3racing use a low quality titanium (as i said), which is brittle but cheap! and not suitable for our needs.
