Look up their densities and you’ll be amazed at what you find. Also check Ti’s Cof vs steel or iron. Think about what kind of coating is on your Ohlins forks. And yes tongue in cheek.
And look up the coefficient of expansion for all. Ain't just friction. I'd have titanium rods if they could get the fatigue life up a couple of order of magnitudes. Expensive parts to replace every couple of years.
