My bad, I was curious before and went looking around and found Ti-6Al-4V and it said that at the Aerospace Metals website. Went back and rechecked, it is only grade 5, curious, they said it was the most commonly used industrial alloy of titanium.
How does one make pivot pins and them work if the metal commonly seizes up when run directly against steel? That was supposed to be one of the bugaboos of titanium rods, that they must have upper end pin bushings as they would not wear directly against steel at all.
