Titanium etching is a subtractive metal machining process which uses specialist etchant chemistry to profile complex, highly accurate precision components.
Precision Micro is the only ISO 13485 (medical devices) and AS 9100 (aerospace, defence and space) accredited titanium etching supplier in Europe, ensuring the quality, stability, reliability and repeatability of our titanium etching service.
The titanium etching process
Etched titanium components
Chemical etching titanium opens up an array of possibilities for applications which require a combination of light weight, 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.
- Chemical etching titanium foils used in satellite fuel tanks ensures they are 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.
