The problem with aluminum is that it was a very difficult process to extract it from bauxite ore, so up to then it was almost a precious metal of sorts. Thus US and Germans used it for special occasions since it was rare due to the difficult process. Only later in WWII did aluminum become common and available to the world, including the Philippines from downed planes. This is why you see aluminum on Philippine weaponry from WWII on. It was no longer a very wealthy man's metal.
