Titanium Corrosion Resistance. Titanium occurs mainly as an oxide ore and is the 4th most abundant metallic element in the Earth's crust. The commercially viable forms are rutile or Titanium dioxide and ilmenite or Titanium-iron oxide, with rutile having the richest Titanium content. First isolated in an impure form in 1887, it wasn't until ...
