How about steel pins in the bones and epicardial pacemaker leads? [1]

I had a chance to take part in pour of several pounds of aluminum at
MIT, a demo for visiting high school students from Roxbury.  They were
to use an induction outfit that would do the melt in, IIRC, a few
seconds.  I opted to leave the building because no one had a clue
about the effect of large high frequency magnetic fields on the
pacemaker lead. [2]

[1] Not to mention that the tiny, metal corkscrew tips of epicardial
    leads typically break off after a few years and migrate within the
    body, usually doing no harm.  But having it yanked hither and yon
    or heated to red would be a whole 'nother story.

[2] No pacemaker, just the lead, for reasons too off topic to get into
    here.
