I recall reading somewhere that the wire was zirconium. Magnesium is too
dangerous and, as I recall, aluminum wire of that size would also be too
dangerous especially in pure oxygen. With both, there is too great a danger
of the wire igniting spontaneously. 

At my job site, we are required to keep aluminium sputter targets and wafers,
etc, away from acid sinks that have hydrogen peroxide in them. Seems that
there was once a fire caused by someone getting the pure aluminum too close
to an oxygen source.
