I’ve cut aluminum sheet metal (not sure alloy) and engraved them but they corroded beyond recognition when near the ground. Same with aluminum can tags, eventually they are really hard to read and occasionally really degraded away.
I recently bought a DYMO m1011 in the case, used. I wanted the more retro version but found a great deal on this one. Does aluminum and stainless steel tape. The embossing should be legible much longer on aluminum and probably near forever on more expensive stainless tape.
