Titanium front axle?

I have a brand new titanium front axle for a rm125. Should I still use the aluminum nut like the oem axle uses or should I try finding a stainless one? I use stainless nuts on most of my titanium hardware mainly because that’s what I was told is best to use with ti. Would a titanium nut be ok? I’m having trouble finding a stainless nut made to the right dimensions but I have a brand new aluminum nut and I can get a ti nut if that would be better. Thanks

Personally, I’d run the Al nut. Perhaps with a tiny bit of suitable anti seize. (Reduce the chances of corrosion/interaction)

I always believed ti doesn't rust or corrode

Run whichever nut you'd like, but make sure to use anti-seize. A zinc coated steel nut is probably the least likely to cause problems, but they'll all be fine when used with anti-seize. If it were me, I'd run the aluminum nut.

Make sure you use the correct torque value and check it somewhat often. Fancy fasteners are great for some weight savings (on the bike and wallet), but they require more care and maintenance.

One of it’s good properties.

Sometimes two metals that are both normally corrosion resistant can “react”

Apparently stainless bolts, used on AL trailers should be coated with “Duralac“, for EG
