If I may, let me quote from Edward Rosenberg's article about
titanium, "Noble Challenge," from the October 2001 issue of AJM:
"The standard wheel and brush finishes used in the jewelry industry
can be applied to titanium pieces, although more agressive silica
base compounds and longer finishing times are required. Also, both
rotary and vibratory mass finishers can be used, although more
aggressive cutting media and longer cutting times are required.
Titanium is often finished with the same cutting media used on steel,
rather than the more familiar compounds used for gold and silver.
Once again, though, the choice of alloys will affect the final
result:The harder the material, the higher polish it will take."
Hope this helps.John Shanahan
