Copper

Copper needs max power at 2W. Dark result.

Copper needs max power at 2W. Dark brown-black mark.

High power needed for copper. Dark brown-black result.

Copper still needs high power. Dark mark, slight bronze tinge.

Copper reflects IR; needs high power. Result is dark brown-black mark.

Copper is reflective — fiber can damage tube at high power. Keep below 80% and test carefully.

Copper is highly reflective at 1064nm and 2W is at the extreme limit. Results will be very light/minimal. Not a recommended application for the 2W F1 — the F1 Ultra (20W fiber) is the appropriate machine for copper. Included here as a best-effort starting point only. | Freq: 30kHz, line interval: 0.03mm

Copper reflectivity at 1064nm makes marking difficult at 30W. Longer pulse width + multiple passes recommended. Full watt output, slow speed. Still marginal — 50W+ is the community consensus for reliable copper engraving. Based on omglaser.com 60W copper settings scaled proportionally. | Freq: 30kHz, pulse: 500ns, line interval: 0.02mm

Copper is highly reflective at 1064nm — 20W is marginal. Run at maximum power, slow speed, multiple passes. Result may be shallow or inconsistent; copper engraving is more reliable at 50W+. Based on heatsign guide + community notes. | Freq: 30kHz, pulse: 200ns, line interval: 0.04mm

Copper is reflective and challenging for fiber lasers. At 88% the LP4 can mark copper but results are less consistent than stainless or aluminium. Use the stand for copper — handheld is too unstable for this material. Polished copper may need two passes.

What are the best laser settings for Copper?

A top-rated community setting for Copper on the LaserPecker 4 is speed 1000 mm/s, power 95%. There are 11 community-tested settings for Copper across 6 machines on this page.

Do I need air assist for Copper?

9% of the community settings for Copper use air assist. Air assist is optional for most operations but can improve edge quality on cuts.

Do I need a fiber laser for Copper?

Fiber lasers can mark Copper directly without any coating. There are 11 fiber laser settings on this page. Diode and CO₂ lasers may require a marking compound (like Cermark) to achieve a visible result on bare metal.
