Magnesium and aluminum are two chemical elements. The critical difference between aluminum and magnesium is that aluminum is corrosion resistant, whereas magnesium is not. The atomic number for aluminum is 13, and the atomic number for magnesium is 12. Aluminum is less expensive.
It also has a lower density and excellent thermal and electrical conductivity. It can be easily recycled. Aluminum has a specific gravity of 2.7, while magnesium has a specific gravity of 1.7. Aluminum is stable, and magnesium is less durable, as it bends easily under stress.
There are two elements that have a lot in common. These are aluminum and magnesium. The uses for aluminum probably far outweigh the uses for magnesium. That is to say that people use aluminum more than they use magnesium. Aluminum is used to make vehicles, appliances, and even paint. Magnesium is used in cameras and luggage. Aluminum is actually heavier than magnesium.
Magnesium can actually be found in the ocean, and there is a lot of it in the ocean. If you wanted to make something that will not rust and corrode, then you should use aluminum because magnesium will corrode. Magnesium costs more than aluminum. People do not ingest aluminum, but they may ingest magnesium because plants and animals need it.
