Aluminum"s properties enhance its use in trade and manufacturing. "
Aluminum has a face-centered cubic (FCC) crystalline structure, which allows for efficient packing of atoms and provides strength and stability. Aluminum atoms are held together by metallic bonds, where valence electrons are delocalized and shared among neighboring atoms. This bonding results in the cohesive forces that give aluminum its strength. When exposed to air, aluminum rapidly forms a thin layer of aluminum oxide (Al2O3) on its surface. This layer acts as a protective barrier, preventing further oxidation and corrosion of the underlying metal. It self-repairs if damaged, which contributes to aluminum's corrosion resistance.
There is a combination of high strength and lightweight in only a few materials in nature. The high strength of some aluminum alloys is comparable to the strength of steel. Aluminum can be deformed by various methods of forming metals. Aluminum can also be connected by welding, soldering, gluing, and riveting. Some aluminum alloys can regain their original state after the force is removed if they are affected by force or impact in a certain range. Aluminum is the most conductive metal after silver, copper, and gold, which is why it is used in the manufacture of kitchen utensils, water, and oil heat exchangers.

In metallic bonding, valence electrons are not tightly bound to specific atoms but are free to move throughout the metal. This delocalization facilitates the rapid transfer of heat and the flow of electricity, resulting in aluminum's high thermal and electrical conductivity. The face-centered cubic structure of aluminum allows for easy deformation without a significant disruption of the metal's internal arrangement. The metallic bonding, with its delocalized electrons, enables the atoms to slide past each other, making aluminum highly malleable and formable.
Aluminum has a relatively low melting point, which enables efficient recycling processes. Recycling involves melting aluminum scrap, removing impurities, and reforming it into new products, saving energy compared to primary production. Aluminum's reactivity is mitigated by the formation of the protective aluminum oxide layer. This oxide layer quickly forms on the surface when aluminum is exposed to oxygen, preventing further reaction and corrosion.
