Coated Metals

Coated Metals Overview

Coated metals are a diverse class of manufactured products that typically consist of a polished metal substrate coated with another material. Examples of coated metals include: AlumaMark®, DuraBlack®, anodized metals, painted metals, and powder coated metals. Laser processing of coated metals is performed using a 10.6 or 9.3 micron CO2 laser. Some coatings also absorb 1.06 micron fiber wavelength, but because the underlying metal also reacts to this wavelength it can be challenging to match the quality of a CO2 process. Laser marking or engraving of coated metals is achieved when laser energy is used to modify or remove the coating, creating a contrasting mark.
