The process can be applied in a bath or with brushes and other applicators. Colors can be controlled and laid down individually by using masking techniques. They are ductile and can be formed with some effort. It takes a heave hand to forge titanium, but it work hardens slowly. Industrially it is vacuum or inert gas annealed.
Titanium can be heat colored, though the results are less predictable than anodizing.
It is corrosion resistant and hypoallergenic. Titanium Breakthrough Multi-Etch pretreatment makes bright colors available on titanium. Now, without strong acid mixtures, high voltage anodized color can be produced on titanium. Properly used, it preserves surface finishes, erases color errors and expands the color range on titanium. Surface finish and hardness will vary.
