In our last article on aluminum facts, we talked about its history, its discovery, its characteristics and its abundance. In this article, we are going to learn about random aluminum fun facts that we are pretty sure will leave you surprised. So, without wasting time any further, let us begin with our list of facts…
Random Aluminum Fun Facts: 1-5
1.We learned in our previous article that discovery of aluminum was really difficult and hence, its cost was very high. It was in mid 19th century known as the Metal of Kings.
2. Just how costly was aluminum? Well, a kilo of aluminum was priced at USD 1,200 back in 1852. Compared to this, gold was cheaper at USD 664 a kilo.
3. In 1854, the price of aluminum went down a little because potassium used in aluminum production was replaced by the cheaper alternative of sodium. By 1859, the price of aluminum had gone all the way down to USD 37 a kilo.
4. As of today, aluminum is produced or extracted from its ore using Hall-Héroult process where electricity is used. This is a method of mass production. After the introduction of this process, the price of the element went all the way down to USD 1.20 per kilogram by 1895.
5. As far as Hall-Héroult process of extracting aluminum is concerned, it requires a lot of energy. 1 metric ton of aluminum can be extracted from 17.4 megawatt hours of electrical energy. In comparison, only 1/3rd of that power is required for producing exact same amount of steel.

6. When it comes to recycling aluminum, the amount of electricity required is far far less. Only 5% of the energy is consumed in recycling the same amount of aluminum (1 metric ton).
7. We know that aluminum doesn’t rust when left open in air. It only forms a thin layer of aluminum oxide on the surface, preventing further corrosion. However, there is a way for making aluminum rust. It has to be oxidized using mercury.
8. Do you know the name of the primary ore that is used for extraction of aluminum? It is known as Bauxite.
9. Rubies! Aren’t they beautiful? Did you know that rubies are actually aluminum oxide crystals with a few atoms of aluminum replaced by a few chromium atoms, giving rubies their characteristic color?
10. Chou-Chu was a general of ancient China during the third century. Upon digging his tomb, historians found a piece of jewelry. 85% of the material of the jewelry was actually aluminum. This has left historians wondering exactly how the aluminum was extracted back then. So yes, while credit for discovery of aluminum goes to Europeans, ancient people did it long time back.
