Some Knowledge About Aluminum

Aluminum is a very common raw material in industrial manufacturing. Here are some knowledge points about aluminum.

1. Why is aluminum called a flying metal?

The density of aluminum is small, only 2.7g/cm³, and there is a dense Al₂O₃ film on the surface, which prevents the internal aluminum from reacting and is not easily oxidized. It is a commonly used material for aircraft. 70% of modern aircraft are made of aluminum and aluminum alloys, so it is called a flying metal.

2. Why is aluminum trivalent?
In simple terms, the outer electron configuration of aluminum atoms is 2, 8, and 3. The outermost electron number is not full, the structure is unstable, and 3 electrons are easy to lose, so it often shows positive trivalence. However, it is obvious that 3 electrons are more stable than the outermost electron of sodium and the outermost two electrons of magnesium, so aluminum is not as active as sodium and magnesium.

3. Why do aluminum profiles generally need surface treatment?
If aluminum profiles are not surface treated, they will not look beautiful and will be easily corroded in humid air. This makes it difficult to meet the requirements of high decorativeness and strong weather resistance for aluminum profiles in building materials. In order to improve the decorative effect, enhance corrosion resistance and extend service life, aluminum profiles generally require surface treatment. We also provide surface treatment for the aluminum busbars produced by our company according to customer requirements.

4. Why is aluminum more expensive than iron?
Although the reserves of aluminum in the earth's crust are greater than iron, the production process of aluminum is much more complicated than that of iron. Aluminum is a relatively active metal element. Smelting requires electrolysis. The cost consumed in the entire production process is higher than that of iron, so the price of aluminum is higher than that of iron. Aluminum profiles can be developed into aluminum profiles of different specifications according to the needs of different customers. This is the special profile mold opening, which is suitable for any industrial industry. Moreover, the aluminum profile frame is very time-saving and labor-saving when building. It can be assembled and designed according to the drawings provided by customers, and then quickly assembled on site, saving a lot of manpower and material resources and greatly saving the cost investment of the enterprise.

5. Why do soda cans use aluminum cans?
Aluminum cans have the following advantages: not easy to break; light weight; opaque. The pressure in soda is greater than normal pressure, and there is no need to worry about deformation under pressure. Moreover, aluminum cans can ensure the pressure of carbon dioxide in soda, so that soda can achieve a better taste effect.

6. What are the uses of aluminum?
Aluminum has many uses, but it can be summarized into the following major uses: Aluminum Uses Aerospace aluminum is used to make aircraft skins, fuselage frames, beams, rotors, propellers, fuel tanks, wall panels and landing gear struts, as well as ships, rocket forgings, spacecraft wall panels, etc. It is widely used in packaging for beverages, food, cosmetics, medicines, cigarettes, industrial products, etc. Aluminum for transportation can provide all kinds of aluminum alloy materials for automobiles. Large porous profiles for subways and light rails fill the domestic gap and meet the requirements of subway localization. It is used to manufacture automobiles, subway vehicles, railway passenger cars, high-speed passenger cars, body structures, doors, windows and shelves, automobile engine parts, air conditioners, radiators, body panels, wheels and ship materials.
