Marking Raw Metals: Aesthetics and durability

Can raw metals such as bare anodized aluminum or stainless steel be marked with a laser? 

Raw metals without a coating shouldn’t be marked. Marked bare anodized aluminum will leave a low-contrast white mark on a silver background. Stainless steel will leave a blackened carbon mark if given enough power, but the amount of heat needed to generate the black mark can distort the metal and graphics.

Marking a pre-coated sheet (e.g. DuraBlack) or sprayed sheets (e.g. CerMark) protects the integrity of the base metal and leaves the metal surface intact and fully protected.
