Proper aluminium oxide has fairly different properties to stuff that are aluminium with just an oxide layer. So can we class things just with an oxide layer as aluminium oxide or not? im asking this becuase going by this logic then aluminium foil would be reffered to as aluminium oxide foil and it has very different hardness compare to proper uses of manafactured aluminium oxide such as tools

No because naturally occurring oxide layer is <10nm thick. Even for aluminium alloys (like a climbing carabiner for example), manmade anodised layers are unlikely to be more than about half a mm thick so are negligible in the overall mechanical properties.
