Maybe if it were tougher that way - but then there's still no reason
for it to explode.

In reality, "neutronium" means a form of matter composed entirely of
neutrons.  However, neutrons do not bind to each other and decay
rapidly, except in extreme conditions such as the core of a neutron
star.  Even if magically stabilized, neutronium would be expected to
be a fluid rather than a solid.  A ridiculously dense fluid in which a
speck barely visible with a magnifying glass would have a mass of many
tonnes.

In a science fiction setting it could mean anything at all.  If it's a
suitable material for making a knife from, it probably refers to a
material named after Jimmy Neutron: Boy Genius rather than anything
related to the real meaning of the term.
