If those keys were brass or aluminum then my experience has been the same as yours. I use Cermark only on steel.

With my 80w Triumph, I can get a 'reasonably' good etch on brass, much more so than my lower powered lasers.
But as good as it seems, if you soak the lasered brass in water for few minutes, the black just comes off...
The only way I'll sell lasered brass is if it's ok with the customer to clearcoat it afterwards. Works great,
seals the Cermark and it ends up looking like gloss black paint.

I Cermarked some pure silver the other day, came out nice and dark. Needed a lot of power as silver is such a good thermal conductor.
