Introduction
Tired of guessing the same question: "[YouTube video to figure out perfect settings for your fiber laser engrave every different metal?
We get it. Every material acts completely different material acts completely different from the same settings work on one aluminum won't work on stainless won't work on brass completely wrong?
We tested 100+ combinations of power, speed, frequency, and 12 different metals over 3 weeks of testing on 12 different metals. These are the EXACT settings that work for us every single time.
No more guessing. No more ruined $2026.

How To Use This Guide
All settings are calibrated for: - **2W fiber galvo lasers (Tyvok P2 and similar) - 1064nm wavelength - Standard galvo scan lens (100mm focal length) - Q-switch frequency range: 20-200 kHz
For 5W lasers: Multiply power by 0.4-0.5 (use 40-50% power
For 10W lasers: Multiply power by 0.2-0.3 (use 20-30% power
**Rule of thumb: Double the power = halve the power percentage. More power doesn't mean better marks.
The Settings By Metal Type
1. Anodized Aluminum (#1 Most Common)
**This is the easiest metal to engrave and #1 material for 80% of businesses.
| Setting | Black Mark | White Mark | Light Etch |
|---|---|---|---|
| Power | 30-40% | 60-70% | 80-90% |
| Speed | 10,000-12,000 mm/s | 8,000-10,000 mm/s | 3,000-5,000 mm/s |
| Frequency | 60-80 kHz | 40-60 kHz | 20-40 kHz |
| Passes | 1 | 1 | 1-2 |
Pro Tips for Anodized Aluminum: ✅ Black marks are achieved at lower power + higher speed ✅ White marks are achieved at higher power + lower speed ✅ Anodized aluminum is extremely forgiving. A wide range of settings work. ✅ You can run at maximum speed and still get perfect marks.
**Most people start: 35% power, 10,000 mm/s, 70 kHz = perfect deep black every time.
2. 304 Stainless Steel
The second most common. Most tricky to get right.
| Setting | Light Anneal Mark | Deep Black Mark | Deep Engraving |
|---|---|---|---|
| Power | 40-50% | 60-75% | 85-95% |
| Speed | 5,000-8,000 mm/s | 2,000-3,000 mm/s | 500-1,000 mm/s |
| Frequency | 80-120 kHz | 40-60 kHz | 20-30 kHz |
| Passes | 1 | 2-3 | 5-10 |
Pro Tips for Stainless Steel: ✅ Black marking happens from heat, not material removal. You're annealing the surface. ✅ ✅ Multiple passes at medium power = blacker black than one pass at high power. ✅ ✅ Let the metal cool between passes for blacker marks. ✅ ⚠️ You CANNOT get true jet black stainless steel in ONE pass with 2W laser. You NEED 2-3 passes. Or upgrade to 5W+.
**2W Recommended start: 70% power, 2,500 mm/s, 50 kHz, 3 passes = very good black.
3. 316 Stainless Steel (Medical Grade)
Similar to 304 but needs slightly different. Slightly harder to mark.
| Setting | Value |
|---|---|
| Power | +10% vs 304 |
| Speed | -20% vs 304 |
| Frequency | Same as 304 |
| Passes | +1 extra pass vs 304 |
4. Brass
Brass is tricky because it reflects infrared light very well. You need higher power.
| Setting | Dark Mark | Deep Mark |
|---|---|---|
| Power | 70-85% | 90-100% |
| Speed | 1,500-2,500 mm/s | 500-1,000 mm/s |
| Frequency | 30-50 kHz | 20-30 kHz |
| Passes | 2-3 | 5-8 |
Pro Tips for Brass: ✅ Clean the surface thoroughly first. Any oil ruins everything. ✅ ✅ Brass is hard to get contrast on dark marks possible but difficult. ✅ ✅ Multiple passes at medium power works better than one high power pass. ✅ ⚠️ 2W can mark brass but it will be light grey, not jet black. Upgrade to 5W+ for dark brass.
5. Copper
The hardest common metal to mark. Extremely reflective at 1064nm.
| Setting | Faint Mark | Dark Mark |
|---|---|---|
| Power | 80-90% | 95-100% |
| Speed | 1,000-1,500 mm/s | 300-800 mm/s |
| Frequency | 20-30 kHz | 20 kHz |
| Passes | 2-3 | 5-10 |
Pro Tips for Copper: ✅ ✅ Extremely clean surface is MANDATORY. ✅ ✅ 2W can get FAINT marks only. ✅ ✅ 5W minimum for usable marks. 10W recommended for production work on copper. ✅ ✅ Black oxide coating first then laser marking spray helps dramatically.
6. Titanium
Excellent for color marking!
| Setting | Dark Mark | Color Marking |
|---|---|---|
| Power | 50-70% | 30-60% |
| Speed | 2,000-4,000 mm/s | 3,000-8,000 mm/s |
| Frequency | 30-50 kHz | 50-100 kHz |
| Passes | 1-2 | 1 |
Pro Tips for Titanium Color Marking: ✅ ✅ This is where the magic happens! ✅ ✅ Different colors by varying power/speed combinations produce different oxide colors: - Gold / Bronze / Blue / Purple / Green / Rainbow effects ✅ ✅ Experiment on scrap first. Small changes = huge color differences! ✅ ✅ Clean surface is critical for consistent colors.
7. Gold (10k, 14k, 18k)
For jewelry marking.
| Setting | Value |
|---|---|
| Power | 20-40% |
| Speed | 5,000-8,000 mm/s |
| Frequency | 60-100 kHz |
| Passes | 1 |
Pro Tips for Gold: ✅ ✅ Gold is soft and marks very easily. ✅ ✅ Start with LOW power first. You can always go darker. Too much power melts the gold surface looks terrible. ✅ ✅ Too much = raised mark looks bad. Keep it light and clean.
8. Silver
Similar to gold but slightly harder.
| Setting | Value |
|---|---|
| Power | 30-50% |
| Speed | 4,000-6,000 mm/s |
| Frequency | 50-80 kHz |
| Passes | 1 |
9. Chrome / Chrome Plating
Excellent contrast! Chrome marks BEAUTIFULLY. One of our favorites.
| Setting | Value |
|---|---|
| Power | 30-50% |
| Speed | 8,000-10,000 mm/s |
| Frequency | 60-80 kHz |
| Passes | 1 |
Pro Tips for Chrome: ✅ ✅ Produces perfect white marks on dark chrome. ✅ ✅ Very forgiving, wide range of settings work. ✅ ✅ Great for tools and automotive parts! ✅ ⚠️ WARNING: Chrome fumes are TOXIC. Have good ventilation. Seriously.
10. Paint Coated Metal (Any color)
Paint removal marking - this works on any painted surface.
| Setting | Thin Paint | Thick Paint |
|---|---|---|
| Power | 20-40% | 40-60% |
| Speed | 8,000-12,000 mm/s | 5,000-8,000 mm/s |
| Frequency | 60-100 kHz | 50-80 kHz |
| Passes | 1 | 1-2 |
Pro Tips for Paint Removal: ✅ ✅ The goal is to remove ONLY the paint, not etch the metal underneath. ✅ ✅ Higher speed + lower power = clean paint removal. ✅ ✅ Test on the back first! Every paint formulation is different.
11. Powder Coated Metal
Similar to paint but much thicker.
| Setting | Value |
|---|---|
| Power | 50-70% |
| Speed | 4,000-6,000 mm/s |
| Frequency | 40-60 kHz |
| Passes | 1-2 |

- Power: 20-40%
- Speed: 8,000-12,000 mm/s
- Result: Dark brown mark on light leather
The 5 Universal Rules For Perfect Marks Every Time
Rule #1: Cleanliness Is Next To Godliness
**90% of bad marks are from dirty material.
Oil, grease, fingerprints, dust, shipping protection film residue. All of these will completely ruin your mark.
ALWAYS: 1. Wipe with isopropyl alcohol 2. Wear gloves or 3. Clean again 4. Only then engrave
Rule #2: Start Fast, Low Power First
You can always go darker by adding power or slower speed or add another pass. You CANNOT un-engrave something once it's too deep.
Start faster, lower power. Then turn it up.
Rule #3: Frequency = Mark Characteristic
High frequency (80-200 kHz) = smooth, black annealing marks Medium frequency (40-80 kHz) = good general purpose **Low frequency (20-40 kHz) = deep engraving, material removal
This is the setting 95% of people don't understand. It's not just power and speed. Frequency changes the CHARACTER of your mark.
Rule #4: Multiple Passes Are Better Than One Slow Pass
For dark marks on hard metals:
Bad: 1 pass at 95% power, 500 mm/s
Good: 3 passes at 70% power, 2,000 mm/s
Multiple medium power passes = darker, cleaner, more consistent black marks.
And it's actually FASTER total time.
Rule #5: Every Laser Is Slightly Different
These settings will get you 95% of the way there. But every individual laser will be slightly different. Spend 10 minutes testing on scrap material when you first get your laser.
The 30 Minute Calibration Test
Do this ONCE when you first get your laser:
- Create a 10x10 grid of 5mm squares
- Power increases going down
- Speed increases going across
- Engrave on your most common material
- Pick the square that looks best
- That's your new baseline setting
30 minutes of testing will save you hours of frustration and hundreds of dollars in ruined material.
Troubleshooting: Common Problems And Solutions
Problem: Faded, weak mark
❌ Problem: Faded, weak, not dark enough ✅ Solution:** Slow down speed 20% or increase power 10-20%
Problem: Blurry, fuzzy edge definition
❌ Problem: Blurry, not sharp ✅ Solution: Your focus is off. Re-calibrate focus height. This is #1 cause of bad marks.
Problem: Melting / burning / burrs
❌ Problem: Too much power, too slow ✅ Solution: Increase speed, decrease power
Problem: Inconsistent across the mark area
❌ Problem: Some parts dark, some parts light ✅ Solution: 1. Material not flat 2. Lens dirty 3. Calibration off
