Nickel tends to be very corrosion resistant. Though these properties are probably diminished by the increased surface area of the porous topology. I run a small forge. Every alloy I've used will corrode way faster if it's not been finished smooth. I can only imagine how fast a metal (even nickel) foam oxidizes.
