Zirconium is a reactive metal and depends on a
passive film for corrosion resistance. Zirconium
is very resistant to corrosive attack in most mineral
and organic acids, strong alkalis, saline solutions,
and some molten salts. It is not attacked by
oxidizing media unless halides are present. Zirconium
is not resistant to HF, ferric chloride
(FeCl3), cupric chloride (CuCl2), aqua regia,
concentrated H2SO4, and wet chloride gas.
The most prevalent use of zirconium, zirconium-hafnium
alloys, and Zr-Hf-Nb alloys has
