Titanium is a reactive metal, meaning it spontaneously
forms as natural oxide film (mainly TiO2)
in the presence of any oxygen. Whenever there
is any amount of air or water in a process
stream or environment, the oxide film forms
and protects the metal from corrosive attack.
If the film is scratched or damaged, it repairs
itself instantly. The highly-adherent film
is exceptionally resistant to a broad range
of acids and alkalis.
This is the main reason why titanium is widely
used for the realization of a wide range of
galvanic/anodising equipments such as Anode
baskets, racks, jigs, serpentine coils.
