Stripping of Electroless Nickel from
Neodymium
---
We have been asked to strip and replate some electromagnets
manufactured from Neodymium (NdFe). These magnets were electroless
nickel plated by another firm and are now peeling. Our concern is
whether or not this material (NdFe) might be damaged during the
stripping process. What stripping solution might be employed?

I have stripped rare earth magnets in a two part electroless Ni
strip , without any ill effects. Just make sure it's in a
non-magnetic tank . The strip was at 60 c and is immersion type from
a local supply house (possibly Udylite on your side ) .

Good luck.
