Laser Marking Parameters by Metal
These are starting parameters for a standard 20–30W fiber laser with a galvo scanner. Always test on scrap material first.
Gold Marking Parameters

|---|---|---|---|---|
| Light annealing (hallmark) | 10–15% | 300–500 | 20–30 | Dark mark, no depth |
| Deep engraving (inside ring) | 40–60% | 100–200 | 30–50 | Shallow groove, 0.02–0.05mm |
| Texture/pattern | 30–50% | 200–400 | 40–60 | Surface modification |
Silver Marking Parameters
| Application | Power | Speed (mm/s) | Frequency (kHz) | Result |
|---|---|---|---|---|
| Foaming mark (logo) | 20–30% | 400–700 | 50–80 | Light raised mark |
| Engraving (serial number) | 50–70% | 80–150 | 30–50 | Shallow groove |
| Light annealing | 15–25% | 300–500 | 20–40 | Subtle dark mark |
Platinum Marking Parameters
| Application | Power | Speed (mm/s) | Frequency (kHz) | Result |
|---|---|---|---|---|
| Annealing hallmark | 20–30% | 200–400 | 20–30 | Dark, high-contrast mark |
| Deep engraving | 60–80% | 50–120 | 30–50 | Clear groove, 0.03–0.08mm |
Titanium Marking Parameters
| Application | Power | Speed (mm/s) | Frequency (kHz) | Result |
|---|---|---|---|---|
