Laser Cutting of Thick Aluminum

Laser Cutting of Aluminum using a CO2 laser

For the CO2 laser, aluminum, is extremely reflective to the CO2 laser’s wavelength.

You need at least 400 watts of CO2 laser power to even attempt to cut a 1 mm thick piece of aluminum and get a good edge quality at a reasonable processing speed.

To cut 1.5mm aluminum most people recommend at least a 1KW CO2 laser.

Laser Cutting of Aluminum using a YB fiber laser

When using a YB Fiber laser the power to cut a 1.5mm thick piece of aluminum would be approaching 1KW.
