Some countries do recycling of aluminium well, Japan for example, most don’t.
Issues with contamination, sorting, pipeline, storage, just to name a few make it hard to implement well.
Last time I checked modern aluminum alloys made it very hard to recycle aluminum waste efficiently. That's still the case, apparently.
Nearly all industrial ones yes, that’s why some countries that care a lot about recycling use easy to recycle alloys for cans, like Japan. They also religiously keep contaminants and other bits of aluminium out.
