After some advice to find a good starting point for test material.

I have S1 with 40w diode laser.

I want to "etch" some stencils to use with a nail art stamp. Doesn't need to be deep just deep enough to hold paint. Making warhammer decal stamps.

We did some engraving with what we thought was stainless with average results, unless we used powder coated.

What would be a suitable metal to engrave or do a couple low power cutting passes to get a suitable depth with?

Brass, aluminium etc?
