How to Laser Engrave Anodized Aluminum: A Complete Guide
To laser engrave anodized aluminum, use a fiber laser or CO2 laser with enough power to remove the anodized layer without damaging the base metal. Focus the beam precisely, and adjust the speed and frequency to match the thickness of the anodized coating. Avoid too much power or multiple passes, which can burn or blur the mark. A good setup ensures clean contrast and long-lasting results.
