TITANIUM
ETCHING

What Is Titanium Etching?
Titanium etching is the process of selectively dissolving away metal using an oxidising reagent. This process allows high volumes of intricate components to be etched in titanium at speed, without affecting the chemical and mechanical properties of the metal.
Titanium is renowned for its strength, light-weight properties and high temperature performance. However, chemically etching titanium is difficult because titanium rapidly forms a protective oxidized coating when exposed to air, a coating that is exceptionally hard to dissolve. Advanced Chemical Etching's unique TiME technique makes producing etched titanium parts possible at extremely tight tolerances.  ACE has pioneered a unique process for acid etching titanium, making us the industry leader for this etched titanium manufacturing technique.

Safer Chemistry, Better Performance

ACE has developed a new, unique safer chemistry that takes chemical etching titanium to new levels of quality and precision. This is still one of the only safer etchants for use with titanium and is unique to ACE. Learn more about our TiME titanium etching technique.

All Metal Grades

Etching can produce complex features and geometries in titanium sheets of all grades, including titanium (Alpha) grades 1-4, titanium (beta) grades 5-38, Nitinol and Kapton Coated Titanium. Our titanium etching process does not affect the chemical and mechanical properties of the metal.

Processing Speed at Production Scale

ACE has vastly increased the processing speeds and rate of chemical etching titanium. Our chemistry has a higher etching capacity and we are one of the few chemical etching companies in the world that can offer titanium etching on a production scale.

Huge Range of Applications

Titanium etching has a huge range of applications in a variety of industries, especially in the medical sectors where there is a demand for lightweight etched titanium components used in implants and medical devices such as pacemakers.

Worth knowing…

Traditionally, Hydrofluoric Acid (HF) has been used as the preferred etchant for the chemical etching titanium, because of its ability to remove the titanium oxide layer. However, HF is a highly dangerous chemical and one we will not use! We use a unique, non-HF chemistry developed at our laboratory in the heart of the West Midlands.
