In Niobium & Titanium
In reading the various posts here, I've seen several times that sanding titanium with aluminum oxide sandpaper will cause oxide problems and related issues with dull colors. I've also seen mentions of avoiding steel media in tumblers. So if those are bad, the question is what is safe to use for removing scratches and for surface finishing? Is silicon carbide okay? I heard from the Multi-Etch folks to use the Scotch-Brite pads that Reactive Metals sells. The RM catalog lists ultra fine and coarse silicon carbide but also a fine aluminum oxide one. (I thought aluminum oxide was bad? ) What do you use and what specific brand(s) work? I have some 3M wet/dry silicon carbide sanding paper. Is that okay?
