What is Nickel Etching?
Nickel etching is a precision, non-contact process that selectively removes material to form intricate patterns from thin metal sheets. By eliminating mechanical stress, it preserves nickel’s corrosion resistance, thermal stability, ferromagnetic behavior, and protective oxide layer—properties often compromised by mechanical processing.
Whether you need EMI/RFI shielding, high-temperature filters, or precision grids as thin as 0.03mm, nickel etching delivers consistent performance across demanding applications.
Our Nickel Etching Capabilities
We deliver the performance that corrosive environments and high-temperature applications demand. Every nickel component is etched to exact tolerances, remains stress-free, and preserves the material’s properties.
Thickness Range
We etch nickel from 0.03 mm to 1.0 mm, enabling ultra-thin EMI/RFI shields, precision filter meshes, and heat-resistant components for extreme environments.
Wide Alloy Selection
We process pure nickel (Nickel 200/201, 270) and specialized alloys including Inconel, Monel, Hastelloy, Invar, and Kovar.
Ferromagnetic Precision
We maintain nickel's magnetic properties during etching, critical for electromagnetic shielding applications where material integrity directly impacts performance.
High-Temperature Stability
Our process preserves nickel's thermal characteristics for components operating up to 1455°C, including heat exchangers, fuel cell plates, and aerospace applications.
Complex Features
With tolerances to ±0.025 mm, we produce fine channels, micro-grids, intricate perforations, and detailed patterns.
Repeatability at Scale
Our process delivers high-volume production of nickel components with exceptional consistency.

Benefits of Nickel Etching Process
Corrosion Resistance
Nickel naturally forms a protective oxide layer, so etched components maintain durability in harsh environments without additional coatings.
Surface Finish
Nickel etching produces smooth, precise edges while maintaining the metal’s inherent hardness and surface quality
Strength at Thin Gauges
Even ultra-thin sheets (down to 0.03 mm) remain structurally strong and dimensionally stable, unlike many other metals.
Dimensional Stability
Nickel’s low thermal expansion (especially in alloys like Invar) ensures etched components hold their shape in extreme temperature cycles.
Our Nickel Etching Process
With our controlled, automated process, we transform your designs into precise components:
Material Selection
Choose a suitable material from our inventory of pure nickel and specialized alloys.
Cleaning & Preparation
Any surface impurities or contaminants are removed from the material to ensure uniform etching across the entire substrate.
Photoresist Application
A light-sensitive coating is applied to both sides of the nickel sheet.
Imaging
Your design is transformed onto the photoresist using UV light.
Chemical Etching
Then the material is immersed in etchant solutions that selectively remove exposed nickel areas.
Stripping and Finishing
Photoresist coating is removed, and dimensions are verified through CMM inspection.
