The long answer would factor in the commercial market for metals as commodities and the relative abundance of magnesium ore and iron ore in certain geographic areas. The short answer, and the one more relevant to chemistry, is that magnesium is higher on the reactivity series than iron, and thus is slightly harder to separate from its compounds.

Can magnesium replace aluminium?
No, magnesium cannot replace aluminum in all applications because they have different properties. While magnesium is lighter and more reactive than aluminum, it is not as strong or as resistant to corrosion. Thus, the choice between magnesium and aluminum depends on the specific requirements of the application.
Would magnesium nitrate react with magnesium?
Yes, aluminum is more electronegative than magnesium thus, resulting in a single displacement reaction. The products would be magnesium + aluminumnitrate
Are magnesium and calcium more reactive with oxygen in the air than is aluminum?
Yes, both magnesium and calcium are more reactive with oxygen in the air than aluminum. Magnesium and calcium readily form oxides when exposed to oxygen, while aluminum forms a protective oxide layer that prevents further reaction.
Does magnesium react with aluminium sulphate?
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
How to tell if something is made from aluminum or magnesium?
One way to distinguish between aluminum and magnesium is by checking their weight, as aluminum is lighter than magnesium. You can also use a magnet, as aluminum is not magnetic while magnesium is. Additionally, you can perform a spark test by scraping the surface of the material with a file and observing the color of the spark produced - magnesium will give off a white spark while aluminum will give off a faint red spark.
Which of these metals will be oxidized by the ions of aluminum?
Metals with a lower reduction potential than aluminum will be oxidized by aluminum ions. For example, magnesium and zinc are metals that can be oxidized by aluminum ions.
How does Magnesium's atomic radius compare to aluminum?
Magnesium has a larger atomic radius than aluminum. This is because magnesium has one more electron shell than aluminum, leading to a greater distance between the nucleus and the outer electrons.
Can magnesium replace aluminium?
No, magnesium cannot replace aluminum in all applications because they have different properties. While magnesium is lighter and more reactive than aluminum, it is not as strong or as resistant to corrosion. Thus, the choice between magnesium and aluminum depends on the specific requirements of the application.
What metals are in duralium?
Alloy of aluminum (over 90%) with copper (about 4%), magnesium (0.5%-1%), and manganese (less than 1%).
Which is the least reactive sodium aluminum or magnesium?
Aluminum is the least reactive among sodium, aluminum, and magnesium. This is because aluminum is more stable due to the presence of a protective oxide layer on its surface, which prevents further reactions. Magnesium is more reactive than both sodium and aluminum.
What compound do magnesium and nitrogen form?
Magnesium and nitrogen can form magnesium nitride (Mg3N2) when reacted together.
Why did Napoleon 3 use aluminum dinnerware?
Aluminum used to be more expensive than gold. In Napoleon's time the chemists hadn't discovered a good way to purify aluminum so pure aluminum was expensive and rare. Aluminum used to be a status symbol because it was more expensive and rarer than gold.
Would magnesium nitrate react with magnesium?
Yes, aluminum is more electronegative than magnesium thus, resulting in a single displacement reaction. The products would be magnesium + aluminumnitrate
What does magnesium combined with?
Magnesium can combine with Aluminum.
Are aluminum prices rising?
compared to a hundred years ago, no, as aluminum was more expensive than silver than.
Are magnesium and calcium more reactive with oxygen in the air than is aluminum?
Yes, both magnesium and calcium are more reactive with oxygen in the air than aluminum. Magnesium and calcium readily form oxides when exposed to oxygen, while aluminum forms a protective oxide layer that prevents further reaction.
What is the disadvantage of aluminum?
Aluminium is more expensive than steel
