If it is a scientific article, or scientific text, then by all means use the most precise term. In this case that would be either Aluminium or Aluminum. Pick the one that you prefer and be consistent in your text. If it is for fiction or a vulgarization essay, then unless you have other reasons to do so, use the term that your readers will find most fitting. In this case that would be Aluminum. PS Note that precision and consistency in scientific writing is not negotiable.
