Chemical Etching Brass

VT machining provides precision chemical etching of brass for customers who need burr-free, stress-free thin-metal parts made to an exact drawing. Brass is free-etching with good conductivity and an attractive gold-toned finish, 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 Brass?

Photochemical machining removes brass 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 brass is free-etching with good conductivity and an attractive gold-toned finish, etching is often the only way to hold very fine apertures and intricate profiles in it economically.

Brass 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

Brass etches crisply and takes decorative finishes well. Common etched brass parts include decorative panels, nameplates, dials and low-voltage contacts. Each is produced to your CAD or 2D drawing, with the open area, pitch and overall geometry made to order.

From Drawing to Delivered Brass Parts

Send us your artwork, the brass 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 Brass?

For Chemical Etching Brass 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 Brass?

Because chemical etching removes metal without mechanical force, Chemical Etching Brass is completely burr-free and stress-free, holding very fine features and apertures that mechanical methods cannot.

Why choose chemical etching for Chemical Etching Brass?

Chemical Etching Brass 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.
