Aluminium, or ‘aluminium’ depending upon which side of the Atlantic Ocean you live, is the 13th aspect on the table of elements and a post-transition metal. It is the most plentiful mineral on Earth behind oxygen and silicon, making it the most abundant metal naturally discovered on the planet, and the second-most used metal globally, behind just iron. It is mainly utilized as an alloy, even if the aluminium material is as high as 99%.
Nearly everyone in the world has used an item consisting of aluminium at some point. This is in large part because of its preferable physical homes:
- Density: 2.7 g/cm ³ at 20 ° C.
- Brinell Firmness: 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 aspects, from abundance to heat capability and tensile strength, aluminium is utilized in an extremely wide range of commercial goods. It is also definitely recyclable and makes up part of the fundamental facilities of the world. Below are the most common and beneficial applications of aluminium in contemporary society.
It is the homes of aluminium that enable its usages to be so prevalent. It is an easily flexible and corrosion-resistant metal, not to mention its capability to be recycled without losing properties.
Among all its characteristics, they stand out.
- Light, yes, however strong, too. The specific weight of aluminium is just 2.7 g/cm3. Thanks to its alloying capability, its strength can be increased without any problem, and with only 1/3 of the weight of steel, for example.
- It is also resistant to corrosion. As a metal, aluminium naturally oxidises to secure against deterioration. To prevent rusting, the material is covered with a thin plastic sheet, electronegative metal or paint.
What, at some minutes, as we saw in the post about polyamide 66 and the thermal break is a downside, according to its use it turns into one of the best residential or commercial properties of the material.
Reflection And Ductility
In addition to being a great conductor, aluminium is also a great reflector of light and heat. That is why we find aluminium in heat-reflective products. At the same time, it is an extremely ductile metal, with a low melting point, a particular that enables it to be shaped very quickly, unlike, for example, steel.
This can be seen in its function as an aluminium foil for wrapping food. Aluminium, even when laminated to a minimum thickness, is waterproof. Another advantage and reason for its use for food storage are that it is non-toxic.
Aluminium is ideal for circuitry power grids, including overhead power transmission lines and regional power distribution lines because it offers a much better conductivity to weight ratio than copper— likewise among a lot of common materials utilized in electrical applications.
As we’ve explained elsewhere on the blog before, the use of pure aluminium is very rare in the commercial world. Usually, the non-ferrous metal is mixed with other metals to create an alloy depending on the desired use.
Rolled Aluminium Products.
One of the few explicit uses of aluminium in more typical daily use, by its more informal title tin foil, is produced through the metalworking process of ‘rolling’, whereby sheet ingots are cast from molten billet aluminium, then re-rolled on the sheet and foil rolling mills to the wanted density (or do not have thereof), or by continuously casting and cold rolling. Impermeable to oxygen and water, it can be used to not only prepare food but likewise to keep it fresh as well, hence its a very unusual day certainly in which you do not identify a bit of tin foil somewhere.
Heat Sinks For Cooling CPU And Graphics Processors.
The heavy thermal, corrosion and biofouling resistance of aluminium alloys, plus its thermal conductivity, have made them the crucial material of choice for many business heat sinks. These are passive heat exchangers that cool a device (normally a microprocessor or graphics card) by dissipating heat from the device to the environment.
Heat sinks are available in the type of the copper foil of a circuit board or a different device and are attached through a variety of techniques consisting of thermally conductive tape or epoxy.
Windows & Doors.
Aluminium has remarkable thermal effectiveness, so windows made using this metal satisfy energy performance requirements. It’s strong, durable and an excellent long-term financial investment as they do not require upkeep and have a long lifetime. Aluminium anodising can be used to protect materials from deterioration or added as a decorative movie.
Building And Construction.
Did you know that the Empire State Building building and construction materials include aluminium? Due to the weight, it’s simple to work with and enables enhanced installation times. Due to the high thermal conductivity, buildings developed utilizing this is kept cool in summer and warm in winter.
Due to its low weight, considerable strength and workability, aluminium is perfect for aeroplanes, including industrial aircraft that are produced en masse. It isn’t just the main product used for the aeroplane shell, but for the seats, too, as it minimizes the weight and saves fuel spend.
