Which Gas Do You Need for Laser Cutting?
The gas you need depends on your laser type and the material being cut:
- Nitrogen — The most common assist gas for laser cutting stainless steel and aluminium. Produces clean, oxide-free edges. Essential for high-quality cuts on non-ferrous metals.
- Oxygen — Used for cutting mild steel and carbon steel. The exothermic reaction between oxygen and heated steel increases cutting speed and allows thicker material to be processed.
- Compressed Air — A cost-effective alternative for general-purpose laser cutting. Suitable for thin mild steel, wood and acrylic. Lower running costs than pure gases.
