A possible simple test for you, Tony.
If there is a surface, or edge, you can access which will be concealed following reassembly, take a sharp knife and cut away a small wafer. With a pair of tweezers, or small needle nose pliers, insert the wafer in an open candle flame. If it puffs into a bright white light, you have magnesium. If it just turns to white oxide, its aluminium.
