Laser Settings for Aluminium (Bare)
Can you laser engrave bare aluminium?
Yes on fibre — with one expectation to set: aluminium engraves grey-white, not black. Its oxide doesn't darken the way steel's does. For black marks, use a MOPA fibre with tuned settings, a post-engrave oxidiser, or laser marking ink.

PrepPreparation & technique
Degrease. High thermal conductivity means aluminium sheds heat fast — it tolerates aggressive settings.
