FEATURES & BENEFITSAlternatives to Hydrofluoric Acid Etching At Wyman · Fluoroboric acid is one of the possible alternatives to hydrofluoric acid. Solutions containing 5 or more percent of fluoroboric acid will be able to uniformly etch titanium. Starting at 150 degrees Fahrenheit this is an effective acid. Also, unlike hydrofluoric acid, hydrogen embrittlement does not occur to titanium treated with fluoroboric acid.
