Laser Settings for Brass
Can you laser engrave brass?
Yes on a fibre laser — brass takes crisp black marks and deep engraving. It's highly reflective, which brings one important rule: tilt the workpiece 3–5° so back-reflection doesn't travel up into your optics. Diode and CO2 cannot mark bare brass.

|---|---|---|---|---|---|
| Brass | Black mark | 200 mm/s | 100% | 1 | 45 kHz |

⚠ Black markTilt reflective work 3–5° — back-reflection damages optics. Very tight interval, 0.001–0.002 mm.
✓ Deep engrave0.02 mm interval, rotate hatch 0/45/90 degrees per pass.
PrepPreparation & technique
Degrease; tilt reflective stock 3–5°. Deep engraving: rotate the hatch angle each pass (0/45/90°).
⚠ SafetyBack-reflection is the machine-killer here. Lacquered brass: verify and remove the lacquer first.
