Inconel’s outstanding mechanical properties make it a preferred material in industries facing extreme environments. However, these same properties can present significant machining challenges. This is where Precision Micro excels. As experts in photochemical etching for more than 60 years, we offer a stress-free, precise, and economical solution for manufacturing complex Inconel components across a range of engineering applications.
Inconel is a family of nickel-chromium-based superalloys engineered for strength, thermal stability, and corrosion resistance. Common grades include:
Yes. At Precision Micro, we have developed a specialist chemical etching process for Inconel that delivers consistent, high-quality results — even for the most demanding applications.
Our approach combines in-house-developed etchants, tailored specifically for nickel-based alloys, with tightly controlled process parameters. This allows us to produce complex geometries with clean edge definition, tight tolerances, and no burrs or mechanical stress.
Because chemical etching is a non-contact, ambient-temperature process, it eliminates the risk of distortion — making it especially well-suited to thin-gauge or intricate components.
We process Inconel sheets from 0.013 mm (0.0005″) up to 2.0 mm (0.080″). Combined with digital tooling and short lead times, our process is ideal for high-precision Inconel parts up to 1500 mm x 600 mm — whether for aerospace, energy, or other critical industries.
When it comes to manufacturing precision Inconel components, capability matters. At Precision Micro, we combine deep material knowledge with specialist facilities and a proven track record in delivering complex parts at scale.
What sets us apart is not only our ability to etch nickel-based alloys like Inconel with accuracy and consistency, but also the supporting infrastructure that ensures quality and reliability at every stage.

Can Inconel 625/718 be chemically etched?
Yes, both grades are suitable for chemical etching with the right chemistry and process control.
What tolerances are achievable?
Typical tolerances are ±10% of material thickness, to a minimum of ±0.025 mm, depending on part geometry.
Is it suitable for prototyping?
Absolutely. Our digital tooling approach allows for fast and cost-effective iterations.
What is the maximum thickness that can be etched?
We can etch Inconel up to 2.0 mm thick.
Do you offer any post-processing or secondary services?
Yes. In-house and through our network of partners, we offer additional services such as forming, plating, and bonding where required.
