VT machining provides precision chemical etching of silver for customers who need burr-free, stress-free thin-metal parts made to an exact drawing. Silver is the highest electrical and thermal conductivity of any metal, and photochemical etching lets us reproduce fine features in it without the mechanical force, tooling cost or edge stress of stamping or laser cutting.
Why Chemically Etch Silver?
Photochemical machining removes silver by dissolving it through a patterned photoresist, so there is no contact force on the part. The result is completely flat, burr-free and free of the work-hardening and heat-affected zones that mechanical and thermal methods introduce. Because silver is the highest electrical and thermal conductivity of any metal, etching is often the only way to hold very fine apertures and intricate profiles in it economically.
Silver Etching Capability
- Foil thickness typically 0.02–1.0 mm
- Minimum feature size around 0.8 × the metal thickness
- Burr-free, stress-free, perfectly flat parts
- Tooling-free — designs are revised in artwork, so prototypes are fast
- High repeatability from the same digital master across volume runs
Typical Applications
Etched silver suits applications where conductivity is the priority. Common etched silver parts include fine electrical contacts, conductive grids and specialised electronics. Each is produced to your CAD or 2D drawing, with the open area, pitch and overall geometry made to order.
From Drawing to Delivered Silver Parts
Send us your artwork, the silver grade and thickness you need, and your quantity. We confirm feasibility, suggest the optimal foil and finish, prototype quickly and then scale to production from the same master. Post-etch finishing such as plating or passivation can be arranged where your application requires it.

Frequently Asked Questions
What materials can be chemically etched for Chemical Etching Silver?
For Chemical Etching Silver we etch aluminum, stainless steel, titanium, nickel, copper, brass, steel, silver, molybdenum, tungsten and invar. Material choice follows your corrosion, precision and application needs.
How fine and burr-free is Chemical Etching Silver?
Because chemical etching removes metal without mechanical force, Chemical Etching Silver is completely burr-free and stress-free, holding very fine features and apertures that mechanical methods cannot.
Why choose chemical etching for Chemical Etching Silver?
Chemical Etching Silver needs no hard tooling, so designs can be revised quickly and produced flat, stress-free and burr-free — ideal for fine-pitch, thin-gauge precision parts.
