The total volume of the electrolyte in alkaline oxidation is 400l.
The maximum length of the part to be blued is up to 0.5m.

The process of alkaline oxidation, ie. burnishing with subsequent processing (anti-corrosive oiling or greasing) is used to protect parts from corrosion during storage indoors.

The layers of oxide obtained by alkaline oxidation are porous, and provide little protection if applied in a humidified atmosphere.
