Titanium Anodizing

OX-Ti is a surface anodizing treatment for titanium alloys which creates a thin compact titanium oxide layer.

Various obtainable colours

Various bright colours can be obtained which are scratch resistant. These are obtained by self-colouring the titanium oxide layer without using pigments or inks. The colours can be used as colour codes to quickly identify similar parts.


Thanks to its high chemical resistance, the biological compatibility of the layer and the absence of pigments, medical parts can also be treated.


Permits eliminating the seize problem typical of titanium alloys.


The OX-Ti treatment transforms the surface of the titanium alloy into a compact layer of titanium oxide. The composition largely depends on the initial alloy.
Layer colour is obtained by self-colouring. No pigments or inks are used.
RoHS Conformity

Wear resistance
High colour durability thanks to the resistance to light wear and scratching of the titanium oxide layer.
Chemical resistance
Excellent chemical resistance, typical of titanium alloys.
Chemical compatibility
Approximate values of compatibility with the coating environment. The actual resistance to the environment must in any case be tested in the field.

Alcohols, ketones (e.g. ethanol, methanol, acetone)
Neutral saline solutions (e.g. sodium chloride, magnesium chloride, brine)
Halogenidric and reducing agents (e.g. sulphuric acid, hydrochloric acid, oxalic acid)
Oxidizing acids (e.g. nitric acid)
Diluted bases (e.g. diluted sodium hydroxide)
Oxidizing bases (e.g. sodium hypochlorite)
