The books you read are likely very out-of-date. The latest research
suggests there is an iron core (e.g.,
http://news.nationalgeographic.com/n...moon-core.html) and
there is certainly iron in lunar rocks.

Lunar rocks are in fact very similar to earth rocks but lack some of the
more volatile elements and water, which is explained very nicely by the
impact theory and not the capture theory - the latter is a highly
improbable event, if not impossible.
