laser engraving tungsten

[jack Halley]

I have a request for dog tags engraved 2 sides, that are made out of Tungsten.
Is this possible?
Is this possible with a 30w laser?

You'll need to use a marking compound, such as Cermark/Thermark and go really slow at full power (like around 5-10S).

Thanks Dan!
