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 Material characteristics anodized aluminum features a thin oxide layer, which forms a protective barrier on the aluminum surface
This oxide layer can be removed by a co2 laser to reveal the underlying bare aluminum, creating a visual contrast The thickness of the oxide layer and the color of the anodized coating can influence the engraving results Typically, standard clear or black anodized. Laser engraving anodized aluminum is equally possible for fiber laser and co2 lasers, as the laser removes the finish and leaves a contrasting design
