Question about Yag dpps 75w laser

Ive got a question for you guys ,

Im planning to engrave/mark hardcoat anodized aluminum , is 75w yag laser going to be sufficient to produce a nice bright logo on black anodized aluminum ?

Thanks

More than enough

Why use a YAg? a simple 20w co2 Galvo will do for anodised aluminium, a YAG will actually burn away the anodising cutting into the aluminium and exposing bare metal that can corrode , a c02 will leach the black dye from the anodising and actually leave the anodising intact
Ask whoever is supplying your machine to do test samples so you know you arent buying the wrong/much more expensive type...

Well , yes I was thinking about the co2 laser but my customer would like to get a brilliant white engraving on class III hardcoat anodized alu. Just making sure that 75 dpss yag is enough to go thru the hard anodize
