Laser Cutting 3mm Brass – Why Demand is on the Rise

Over the last 12–18 months, Cutting Technologies Ltd has seen a noticeable increase in enquiries for laser cutting 3mm brass. Once considered a niche material, brass is now being specified far more frequently across architectural, electrical, decorative and specialist engineering applications.

Cutting Technologies regularly laser cut 3mm brass for customers who need clean edges, tight tolerances and repeatable quality — without the distortion issues associated with traditional cutting methods.

Why Choose 3mm Brass?

Brass offers a combination of properties that few materials can match:

Attractive finish – ideal for visible or customer-facing components

Excellent corrosion resistance – suitable for indoor and outdoor use

Good electrical conductivity – widely used in electrical and control applications

Easy to form and machine after cutting

Strong without being excessive in weight

At 3mm thickness, brass strikes a sweet spot. It’s rigid enough for structural or functional parts, yet still laser cuts cleanly with the right setup.

Can 3mm Brass Be Laser Cut?

Yes — and very effectively when done properly.

Brass is more reflective than mild steel or stainless, which historically made it difficult to laser cut. Modern fibre laser systems, combined with the correct parameters and handling, now allow consistent, high-quality laser cutting of 3mm brass.

When laser cut correctly, 3mm brass produces:

Clean, accurate profiles

Minimal burr (often requiring no secondary finishing)

Tight tolerances suitable for assembly work

Repeatable results for batch production

Typical Applications for Laser Cut 3mm Brass

The company regularly laser cut 3mm brass for:

Decorative panels and architectural features

Electrical components, terminals and busbar parts

Nameplates, signage and branding elements

Precision brackets and fixings

Enclosures, covers and bespoke fabrications

It’s particularly popular where appearance matters just as much as performance.

Design Tips for Laser Cutting 3mm Brass

If you’re designing parts in 3mm brass, a few simple considerations can help keep costs and lead times down:

Avoid unnecessarily tight internal radii where possible

Allow sensible tolerances for mating parts

Keep hole sizes proportionate to material thickness

Batch similar parts together to improve cutting efficiency

If you’re unsure, our team is always happy to sense-check drawings before production.
