Titanium etching is a subtractive metal machining process that uses specialist etchant chemistry to profile complex, highly accurate precision components.
Precision Micro is one of the only ISO 13485 (medical devices) and AS 9100 (aerospace, defence and space) accredited titanium etching suppliers in the world, ensuring the quality, stability, reliability and repeatability of our etching service.
Titanium etching process
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.
