Short answer: Metal etching dissolves a controlled layer with acid through a mask — chemical (wet) etching for nameplates, art and fine parts, and electrolytic/photo-etching for high-precision thin components — giving burr-free detail that machining cannot match.

How Etching Works
A resist mask protects the areas to keep; acid removes the exposed metal to a set depth. It complements Metal Surface Treatment Guide and Metal Stamping Vs Machining; for steel the etchant often follows the grade in Carbon Steel Supplier.
Metals & Etchants
Ferric chloride etches stainless and copper; HCl-based mixes etch carbon steel; caustic etches aluminum. Photo-etching (mask + acid) makes burr-free fine parts for electronics and mesh. Corrosion context in Galvanic Corrosion Guide; conductivity note in Copper Vs Aluminum Wire.
Applications & Safety
Etching makes nameplates, signage, art panels, PCBs and precision meshes. Neutralise and treat effluent per local rules; every base lot ships with a mill certificate per Mill Test Certificate Guide.

Frequently Asked Questions
Metal etching uses an acid and a resist mask to dissolve a controlled layer of metal, producing burr-free detail for markings, art and fine parts.
Ferric chloride is the common etchant for stainless steel marking and decorative etching; the process follows the grade in our stainless range.
For very fine, burr-free thin parts (PCBs, meshes, nameplates) photo-chemical etching beats machining on detail and cost.
