Fiber Laser Cutting
Fiber laser cutting uses a solid-state fiber laser that cuts thin and medium sheet metal much faster than CO2 lasers and handles reflective metals like brass, copper and aluminium well. It is now the standard technology for sheet metal cutting.
What it is
Fiber lasers generate the beam in optical fibre and deliver it with high efficiency, giving a small, intense spot. This means high cutting speeds on thin sheet and reliable cutting of reflective materials that were difficult for older CO2 lasers.
Lower running costs and higher speeds make fiber lasers very cost-effective for sheet metal production.
Typical applications
- Sheet metal parts for fabrication and enclosures
- Stainless steel kitchen and food equipment parts
- Brass and copper electrical components
- Aluminium panels and brackets
- High-volume nested parts
Suitable materials
- Mild steel
- Stainless steel
- Aluminium
- Brass and copper
- Galvanised and coated steel
Points to consider
- Very fine features are possible, but keep slot widths at least around the material thickness.
- Micro-joints (tabs) hold small parts in the sheet; small witness marks remain.
- Use nitrogen assist for bright, oxide-free stainless edges.
- Protective film on stainless or aluminium sheet can be kept on during cutting.
Frequently asked questions
What is the difference between fiber and CO2 laser cutting?
Fiber lasers are faster on thin and medium sheet, more efficient, and cut reflective metals like copper and brass well. CO2 lasers can still give smooth edges on some thick plate and non-metals.
Can fiber lasers cut copper and brass?
Yes. Cutting reflective metals like copper, brass and aluminium reliably is one of the main advantages of fiber lasers over CO2 lasers.
Is fiber laser cutting cheaper?
It usually is for sheet metal, thanks to higher speed and lower running costs.
