A fiber laser marking machine can be used for light metal cutting, but its capabilities are limited compared to dedicated fiber laser cutting machines. Here is what you need to know:
Can a Fiber Laser Marking Machine Cut Light Metals?
Yes, but with limitations:
Works best on thin metals (typically <1mm, depending on laser power).
Suitable for soft metals like aluminum, brass, copper, and stainless steel (thin sheets).
Not ideal for thick or hard metals (requires higher power).
Key Factors for Light Metal Cutting
Laser Power
10W-30W: Can engrave and make shallow cuts (up to 0.5mm).
50W-100W+: Better for cutting thin metals (up to 1-2mm).
Material Type
Aluminum (0.5-1mm): Possible with higher power.
Stainless Steel (0.3-1mm): Doable but slower than dedicated cutters.
Copper/Brass: Reflective metals may require higher power.
Speed & Precision
Slower than industrial laser cutters but offers high precision for small parts.
Multiple passes may be needed for clean cuts.
Applications
✔ Thin metal tags & labels
✔ Precision cutting of small components
✔ Prototyping & light industrial use
Limitations
❌ Not for thick metals (>2mm) – Requires fiber laser cutting machines (500W-6kW+).
❌ Slower than dedicated cutters for production work.
Best Alternative
If you need consistent metal cutting, consider a fiber laser cutting machine (higher power, air assist, and optimized optics).
