The Complete Guide to Laser Engraving Brass

Thinking of engraving brass? It's a fantastic way to create something special, but getting it right depends on the laser you use. For deep, lasting marks on bare brass, a powerful fiber or infrared laser is ideal.

If you're just doing decorative work on coated brass or occasional etchings, a more affordable laser with a marking spray works wonders. Either way, start with small tests to find the perfect speed and power, and your brass projects will turn out beautifully.

Can You Engrave On Brass

Yes, you can engrave brass, but it depends on the laser type you use.

For a deep, lasting mark that's cut into the metal, a powerful fiber or infrared laser is your best bet.

If you're just looking for a decorative mark on coated brass, a less powerful diode laser with a marking spray can also work.

What Is The Best Laser To Engrave Brass

The best lasers for engraving brass are fiber and infrared lasers. Their wavelength is perfectly suited to creating deep, permanent marks on bare metal.

While other lasers, like diode and CO2 models, can't engrave brass directly, they can be used to make decorative marks with the help of a special laser marking spray.

Best 4 Affordable Laser Engravers for Brass

Looking for value? Here are four affordable laser engravers that offer brass engraving or etching capabilities, each with strengths and limitations to consider.

1. Falcon A1 Pro

The Creality Falcon A1 Pro is a super user-friendly laser engraver that's safe to use at home because it's completely enclosed.

What makes it stand out is its two-in-one laser system: one laser is great for cutting and engraving materials like wood and acrylic, while the other is perfect for putting a lasting mark on metal, like brass.

It's a great option for anyone who wants to work with a lot of different materials without needing a separate machine for each.

2. OMTech Galvo 20W

This machine is a great choice if you're serious about engraving metal. The OMTech Galvo 20W is a fiber laser, which means it's specifically designed to engrave and mark metal surfaces like brass, stainless steel, and aluminum with incredible speed and precision.

Its "Galvo" technology is what makes it so fast—it uses mirrors to move the laser beam, so it's perfect for detailed projects and batch jobs.

3. AtomStack A24 Pro 20W

The AtomStack A24 Pro 20W is a powerful diode laser that's best for cutting and engraving materials like wood, acrylic, and leather.

Its high 20W power rating is great for cutting thicker materials in just a few passes.

While it can't engrave bare metal like brass, it's an excellent, versatile choice for creators who work with a wide range of organic and plastic materials.

4. ACMER P2 2W

The ACMER P2 2W is a compact and very user-friendly laser engraver. Its 2W diode laser is perfect for beginners and hobbyists who want to do light engraving on softer materials like paper, cardboard, thin wood, and leather.

This machine is a great entry point into the world of laser engraving, allowing you to create small, detailed projects with ease, though it's not meant for cutting thick materials or working with metal.

Can A 20W Laser Engrave Brass

Yes, a 20W laser can engrave brass, if it’s the right type of laser.

• A 20W fiber laser with ≈1064nm is ideal, giving clean, durable engraving.
• A 20W infrared laser (solid-state or fiber‐delivered) also helps, although it might produce shallower etches.
• A 20W diode laser by itself will struggle on bare brass; it may work with paint, marking spray, or if the brass is coated.

But for deep, clean, and long-lasting engraving and cutting, fiber or strong IR lasers outperform diodes for brass.

What Metals Cannot Be Engraved

Some metals can be tricky for certain lasers, so it's smart to know the limitations before you invest in a machine for engraving brass.

1. For CO₂ / Blue-diode Lasers

You can definitely work with metals using these lasers, but you'll get the best results on coated or treated surfaces.

While these lasers might not directly engrave bare, polished metals like brass or aluminum, they are excellent at marking things like anodized aluminum or painted surfaces.

If you use a special laser marking spray, you can achieve beautiful, permanent marks on bare metals that would otherwise be difficult to work with.

2. For Fiber / Infrared Lasers

These lasers are fantastic for engraving most bare metals.

You can get deep, durable marks on materials like brass and stainless steel. It’s important to be aware of highly reflective surfaces like polished gold or mirror-finish brass, as they can cause back reflection.

With the right adjustments, like using specific lenses or an air assist, you can still achieve great results on a wide range of metals, including very hard or delicate ones.

DIY Brass Engraving Projects For Home

If you just want to try laser engraving brass at home, here are some fun, simple, and cost-friendly project ideas, all with friendly steps and satisfying results.

• Custom Keychains or Name Tags: Use thin brass sheets (≈1–2 mm). If using an IR or fiber laser, engrave the name or pattern directly. If using a diode laser, clean the surface, maybe sand it lightly, or apply marking spray or paint, then engrave. Finish by buffing to bring out contrast.
• Wall Plaque with Quote or Image: Mount a brass plate onto a wood backing. Use a fiber or IR laser to etch the design deeply. Use darker fill or patina (oxidizer or chemical wash) to enhance contrast between engraved areas and shiny brass.
• Candle Holders or Coasters: Brass coaster blanks engraved with designs (patterns, monograms). For a heat-safe finish, use laser-engraved brass, then seal with clear lacquer to protect from moisture.
• Jewelry or Pendants: Thin brass discs cut or punched out. Engrave initials or symbols. Polish edges, use jump rings, and add cord or chain. Fiber or IR lasers give sharp lines, but even lower-power machines can produce decorative etchings with coatings or sprays.
• Home Decor Signs: “Home”, “Welcome”, or custom name sign in brass, back-lit, or framed. Use cut-out or etched brass pieces attached to wood or acrylic.

In all cases, safety is the highest priority. You must use eye protection, ventilation, and a secure setup. Test on scrap brass first to dial in power and speed. Practice gives better results, and small imperfections often add charm.

Final thoughts

Thinking of engraving brass? It's a fantastic way to create something special, but getting it right depends on the laser you use.

For deep, lasting marks on bare brass, a powerful fiber or infrared laser is ideal. If you're just doing decorative work on coated brass or occasional etchings, a more affordable laser with a marking spray works wonders.

Either way, start with small tests to find the perfect speed and power, and your brass projects will turn out beautifully.
