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.
