The same Google search threw up that chromium can be plated on to copper
bits instead of iron, as a solder barrier. It didn't mention nickel,
possibly because the solder goes through the nickel and attacks the
copper. Of course, bright chrome plate is nearly impossible to 'tin',
but rough plating may be better. Chromium is easy to plate BUT
HEXAVALENT CHROMIUM IS HIGHLY TOXIC AND CORROSIVE SO DON'T MESS WITH IT
UNLESS YOU REALLY KNOW WHAT YOU ARE DOING.
