There are a number of metals that you can engrave (mark) with your laser. Get a copy of the JDS catalog and study it. You can do a lot of things with various metals and JDS has most of them on hand.

Rich you seem to single me out as being wrong, if you read my post you will see it clearly it says MARK and not engrave or etch.

CO₂ lasers do mark some metals. Anodized aluminum marks very well as do some steels - no Cermark required.

You said "the co2 does not engrave metal it will mark metal with cermark...". I interpreted that as you saying that Cermark was required in order to mark metals. So I said that a CO₂ will mark some metals without needing Cermark. I made no argument regarding engraving or etching.
