What is titanium etching?
The titanium etching process involves dissolving away metal using specialist etchants to profile complex, highly accurate precision components. With chemical etching, prototype to high volume titanium parts can be made at speed with no stress or burrs left on the metal.
Etched titanium components
Chemical etching titanium offers a range of possibilities for applications that require a combination of lightweight, strength, corrosion resistance and biocompatibility.
- Cranial and dental implants benefit from burr-free openings. Complex aperture arrays and countersinks can be included at no additional cost.
- Ultra-thin battery current collector grids used in pacemakers can be etched from titanium with ultra-fine wires, ensuring reliable energy supply from a smaller footprint.
- Titanium brazing foils used in satellite fuel tanks can be made thinner – from 0.010mm – and flatter for easier assembly.
- Combining etching and diffusion bonding ensures complex cooling channels can be incorporated into titanium plate heat exchangers at a fraction of the price of conventional machining or laser drilling.
- Titanium membranes used in hearing aids can be made thinner, stronger and more reliable.
