I strongly suggest using a surrogate key. Not because it is "Djangoesque". Suppose that you use a composite key that includes part_number. What if some time later your company decides to change the format (and therefore values) of that field? Or in general terms, any field? You would not want to deal with changing primary keys.

Use meaningless, autoincremented keys (and that should probably render a composite key useless).
