Engraving Aluminum Alloy

[Liesl Dexheimer]

I have a customer requesting engraving on aluminum alloy which is painted red. Is there any chance I will be able to engrave this without Cermark. I was hoping to engrave through the red to reveal the silver but I have a feeling that I may not be able to laser through it with a 35 watt laser. Thoughts??...

The product specifically is this (https://www.rei.com/product/698028/black-diamond-wired-stopper-nut?sku=6980280108&store=80&cm_mmc=PLA_Google_LIA|404_185363|6980280108|none|e 727bb89-78ca-4186-8934-7988683a1711|pla-420138819108&lsft=cm_mmc:PLA_Google_LIA|404_185363|6980280108|n one|e727bb89-78ca-4186-8934-7988683a1711&kclid=e727bb89-78ca-4186-8934-7988683a1711&gclid=EAIaIQobChMIiIro3cGa3wIVrbSzCh04Fw3dEAQYASAB EgKIN_D_BwE).

I could be wrong, but I suspect those are anodized and no paint is involved.

It says they are color coded anodized for easy identification. I don't see why you wouldn't be able to engrave them.

For what it's worth- those nice brass badges I get from Engraving Specialties? My 80w Triumph will do nothing more than 'polish' the clearcoat that's on them, which I assume is lacquer. It will not ablate it, vaporize it--if I go slow enough it'll darken it some. My intent was to try Cermarking them. Fail-- :)

Enamel or water based acrylic, maybe...

Yay, it worked! I was figuring it might be similar to anodized aluminum. Size 9 pt font. Picture doesn't do it justice. Looks better in person.
