attenuo can be purchased at attenuo.com. This plate is made from 3mm thick marine grade 316 stainless steel. Claims to protect from:
- fire damage
- water damage
- ink fade
- accidental discarding
As usual, the straight punch method is one I find to be fastest and most user friendly.
Heat Stress Test
Some discoloration and negligible amount of warping. No data loss.
Corrosion Stress Test
In this case the Attenuo was too wide to fit flat in the bucket and thus was only partially submerged. A nice acid bath (left side) actually makes the Attenuo more legible. Although the dark lines of the template get erased, it’s etched deep enough that the template itself remains legible.
Crush Stress Test
No data loss.
