Laser engraving aluminum
Anodized aluminum laser engraving is a well-known process. Laser etching of aluminum can be seen as a selective laser material removal because the laser removes the anodized layer from the aluminum piece. This results in a high contrast mark between the color of the anodized aluminium and the laser induced marking. Laser engraving of aluminum can be performed with either a CO2 or a fiber laser based system.Ask an expert
Why use a laser for anodized aluminum marking?
Fast and reliable technology
Laser engraving of aluminum allows efficient and rapid marking of an identifier on an anodized aluminum surface, even in harsh environments where the material temperature is over 500 degrees Celsius.
Robust and permanent markings
Laser etch aluminum surfaces can withstand high temperature annealing, heavy salt spray testing and intense UV exposure.
Low maintenance, no consumables
Laser etching systems for anodized aluminum are very low maintenance and consumable free.
Repeatable high contrasts marks
Laser engraving of aluminum allows generation of a high contrast between the anodization color and the laser marked identifier.

In addition to marking identifiers such as logos, barcodes and serial numbers, laser marking can be used to modify the surface finish of an entire part an aluminum extrusion, for example. This can be used to eliminate the extrusion lines that are often still apparent on the surface after the anodization process.
