Aluminium, or ‘aluminum’ depending on which side of the Atlantic Ocean you reside, is the 13th element on the periodic table and a post-transition metal. It is the most abundant mineral on Earth behind oxygen and silicon, making it the most abundant metal naturally found on the planet, and the second-most used metal globally, behind only iron. It is largely used as an alloy, even if the aluminium content is as high as 99%.

Almost everybody in the world has used a product containing aluminium at some point. This is in large part because of its desirable physical properties:

• Density: 2.7 g/cm³ at 20 °C
• Brinell Hardness: 245 [-] at 20 °C
• Tensile strength: 90 MPa at 20 °C
• Melting point: 660 °C
• Specific heat capacity: 900 J/(kg·K) at 20 °C
• Electrical resistivity: 2.6E-8 Ω·m at 20 °C
•  

Due to all these factors, from abundance to heat capacity and tensile strength, aluminium is used in a remarkably wide range of commercial goods. It is also infinitely recyclable and makes up part of the foundational infrastructure of the world. Below are ten of the most common and useful applications of aluminium in modern society
