No, induction is used along with the axiom of infinity to construct a set which we label the integers. Aleph-0 is then defined to be the cardinality of this set. The existence of an inductive set AND induction mean that our model must contain the integers (or somethingl like it) to satisfy the ZF axioms.
This doesn't address the issue that you used
'the axiom of infinity induction'
the last word and the first 4 are understood, we just don't know what you mean whe you put the together.
In all honesty there are bigger issues - the ones I drew your attention to above.
secondly, whatever the axiom of infintiy induction is it would appeart to allow us to state, that because
n>n-1 that aleph-0>aleph-0
that should tell you that since aleph-0 is NOT and integer you can conclude nothing about aleph-0 statements based purely on induction on the integers. induction only tells you truth or otherwise about the statement P(n) for n an integer. P(aleph-0) makes no sense.
