A fiber laser is the type that cuts metal. Learn why fiber beats CO2 and diode for metal, where high-power CO2 fits for thin sheet, and which laser class you actually need.

Fiber metal laser cutters start around $45,000 and climb past six figures by power and size. See what drives machine price, per-part cutting cost, and how to budget.

How thick can a laser cut metal? It depends on power: ~1kW fiber cuts ~20mm carbon steel/10mm stainless, 6kW reaches ~25mm. High-power CO2 cuts only thin sheet. Full thickness-by-power chart.

Cutting metal needs a kilowatt-class fiber laser, not the 20-100W markers people ask about. See why 20W/40W/100W lasers can’t cut metal and what power cuts steel and aluminum.

Yes – a fiber laser cuts stainless steel cleanly, using nitrogen assist for bright, oxide-free edges. Learn thickness by power, why CO2 wattages fall short, and how it affects the steel.

Yes, but you need a fiber laser. A kilowatt-class fiber cutter cuts sheet metal; high-power CO2 cuts only thin sheet; and diode or low-watt lasers and fiber markers can’t cut metal at all.
