Aluminium is a silvery-white metal, the 13 element in the periodic table. One surprising fact about aluminium is that it's the most widespread metal on Earth, making up more than 8% of the Earth's core mass. It's also the third most common chemical element on our planet after oxygen and silicon.
The most common form of aluminium found in nature is aluminium sulphates. These are minerals that combine two sulphuric acids: One based on an alkaline metal (lithium, sodium, potassium rubidium or caesium) and one based on a metal from the third group of the periodic table, primarily aluminium.
Benefits of Aluminum
Light Weight
A known lightweight metal, it has a specific weight of approximately 2.71 g/cm3. It’s about a third of the weight of steel, which makes it easier and cheaper to transport than most other metals. The strength of aluminium can be adapted using varying alloying elements to provide better benefits including higher strength or easier formability. Because of its lightweight nature, corrosion resistance and ease of fabrication, aluminium sheets are the firm for projects like vehicle panelling, artwork, building cladding and kitchen fitting among other applications
Corrosion Resistance
Aluminium is a corrosion resistant metal that naturally generates a protective coating. The coating formed is extremely thin and is generated when aluminium comes into contact with an oxidising environment. This protective aluminium oxide layer helps protect the surface of the metal from corrosion. Additionally, getting surface treatment such as painting or anodising can further improve the overall corrosion resistance of the metal.
Electrical and Thermal Conductivity
It is an excellent conductor of heat and electricity. Although aluminium is not as conductive as copper it is approximately a third of the weight meaning that an aluminium wire with half the weight of a copper wire would have the same amount of electrical resistance. As a result, it is the chosen material for power transmission lines.
Recyclability
Contrary to what most people think, aluminium is a 100% recyclable and during the recycling process, it retains all of its original properties. During production, it is more cost-effective to use recycled metal than prime metal out of the ground and so, during production, as much recycled material is used as possible.
Reflectivity and Ductility
Another benefit of Aluminium is that it serves as a good reflector. It is used in rescue blankets and light fittings because of its ability to reflect both light and heat.
Odourless and Impermeable
Even with 0.007 mm thickness of aluminium foil, it is still impermeable and doesn’t have a substance taste or smell. This is non-toxic and often used for packaging of the sensitive products including pharmaceuticals and food.
Type of Aluminum
3003 Aluminum
3003 aluminum is pure aluminum with an addition of manganese to increase its strength. As an alloy of aluminum, it has, nominally, 1.2% Mn, 0.12% Cu, and 98.6% Al. It is readily weldable, has a relatively low cost per pound, and can be used in most applications. It does not have the corrosion resistance of 6061 or 1100, but it is an economical alternative to those grades for some purposes.
6061 Aluminum
Aluminum grade 6061 is often called “The Workhorse Aluminum.” It has much better corrosion resistance than 300 series alloys. Other benefits include its high heat welding properties as well as its strength when compared with the same thickness of 250 alloys.
This aluminum alloy can be used for products that experience a high level of wear and tear, such as guttering or furniture with exposed corners. The increased strength also makes it the best option to use in situations where there are high levels of humidity because it has an improved corrosion resistance over other grades.
1100 Aluminum
This is the purest form of aluminum commercially available, as it’s made with 99% min purity. It has excellent workability and ductility. This makes it a great choice for challenging forming operations. Even though this metal does not harden when worked or heated as other metals do, its corrosion resistance and weldability make it very versatile. Its high thermal conductivity also gives it an edge in applications that require thermal conductivity.
Construction
Aluminum is used in construction because of its low weight and corrosion resistance. It’s found in building windows, roofs, staircases, door frames, and more. High-rise buildings, in particular, use a lot of aluminum.
Solar Panels
Solar panels use aluminum extensively. According to a study by the World Bank in 2020, aluminum is the most used material in the construction of solar panels. It is applied to solar panels because it is corrosion-resistant, lightweight, and strong. Plus, the reflectivity of aluminum studs increases panels efficiency. However, the majority of aluminum in solar panels is found in the frames — Photovoltaic cells are mounted to aluminum tube structures.
Consumer Goods
Aluminum finds its way into consumer goods for many reasons. In particular, the reflectivity makes it aesthetically pleasing and the low density reduces products’ overall weight. It’s little wonder, then, that the frames of things like laptops, smartphones, TVs, microwaves, and other appliances are often aluminum.


Architecture
Aluminum is used in architecture for many of the same reasons as construction. Because it has an excellent strength-to-weight ratio, architects can frame large spans of skyscraper glass with it.The metal’s formability means it can be processed into complex shapes, and its reflectivity makes for aesthetically pleasing features. Attractive aluminum features may serve structural or purely aesthetic purposes. The Empire State Building is a prime example of the decorative use of aluminum, as it is found in the tower’s ornamental trim, window spandrels, and elevator doors.
Packaging
Aluminum is used in various types of packaging because it’s formable, lightweight, and resistant to corrosion. Aluminum is perfect for applications like: foil packaging, cans, bottlecaps, and food containers. Aluminum is excellent at protecting food and beverage products from UV rays. It is also non-toxic which is essential for food packaging.
Alloys
Aluminum can be alloyed with copper, lithium, zinc, manganese, magnesium, or silicon. Additionally, small amounts of lead, chromium, zirconium, bismuth, titanium, and nickel can also be added. All told, there are around 300 types of aluminum alloy, 50 of which are widespread. These alloys all have varying properties. For example, the alloys used for aerospace and automotive parts are lightened with the addition of lithium, while alloys in building and construction are strengthened to manage heavy building loads.
Steps In Aluminum Production And Manufacturing
Step 1: The Bauxite Mining Process
Aluminum is not found in its pure form in nature and needs to be extracted from bauxite. Bauxite is a type of sedimentary rock featuring traces of aluminum. This rock is the world's main source of aluminum, and experts must refine the sedimentary rock to create alumina. Most countries have bauxite deep below the earth's surface, but the material is more abundant in tropical zones. Aside from Africa and South America, China, India and Indonesia are top providers of bauxite rock. Bauxite is primarily used in the aluminum-making industry, but there is a place for the sedimentary rock in the adhesive, cement and chemical fields as well.
Step 2: Turning Bauxite Into Alumina Through The Bayer Process
The second step in aluminum production is alumina refining. To separate alumina from bauxite, the sedimentary rock is exposed to caustic soda at extreme temperatures. Alumina can be removed from bauxite, but the process requires the use of precipitator tanks in a refining facility.
Step 3: Alumina To Aluminum With The Hall-heroult Process
Once alumina is formed, it needs to undergo a smelting process, called the Hall-Heroult process, to produce pure aluminum. The smelting process involves extracting aluminum by methods of heating and melting.
Charles Hall and Paul Heroult simultaneously and independently invented the Hall-Heroult process in 1886. The process is still used today to make aluminum.
Step 4: Aluminum Is Fabricated Into Finished Products
After aluminum is molded, it's distributed to manufacturers who then turn it into consumer products. A manufacturer will create new aluminum products by remelting them and adding alloys or other materials they need. Pure aluminum does not feature great tensile strength. For this reason, it's often alloyed with small amounts of different materials, such as copper, iron, or titanium, to make it stronger or give it other properties. Manufacturers will then recast the mixture into the desired shape.
Step 5: Aluminum Recycling
Since aluminum is 100 percent recyclable, the manufacturing process doesn't end once it reaches the consumer. Many recyclable aluminum products undergo a secondary production process. Secondary production is the process of turning scrap into aluminum that can be used again in the manufacturing of another product.
Step-by-Step Guide to Cleaning Aluminum
The cleaning process of aluminum is relatively straightforward, and your method and effort may depend on the level of dirt, grime, or oxidation present. Here’s a step-by-step guide on how to clean aluminum:
Step 1: Preparations
Ensure that the aluminum item is free and free of any loose dirt or debris. If the aluminum is anodized (coated with a protective layer), don’t use harsh chemicals that can damage the surface.
Step 2: Basic Cleaning
Create a cleaning solution by mixing mild dish soap with warm water. Dip a soft-bristle brush or sponge in soapy water and gently scrub the surface of the aluminum. Pay special attention to any dirty or stained areas, especially corners.
Step 3: Rinse
Rinse the aluminum item thoroughly with clean water to remove soap residue.
Step 4: Stubborn Stains
If stubborn stains or spots remain, make a paste using baking soda and some water. Apply the paste to the stains or spots and gently rub with a non-abrasive scrubbing pad. Rinse thoroughly.
Step 5: Oxidation Removal
Over time, aluminum reacts with oxygen to form aluminum oxide. This appears as white or gray powdery residue on the aluminum surface. If you notice oxidation, mix a solution of equal proportions of white vinegar or lemon juice and water. The acidic content in the lemon juice or vinegar makes these solutions active against oxidation.
Step 6: Aluminum Cleaner
If you have a heavily oxidized aluminum item, and the above methods aren’t effective, you can use a commercial aluminum cleaner like Star Brite following the manufacturer’s instructions.
Step 7: Polishing
After cleaning, you can use an aluminum wax or polish to bring back the shine and protect the surface. Apply a small amount of polish or wax to a clean, soft cloth and buff the aluminum surface until it shines. Follow the product’s instructions for the best results.
Step 8: Drying
Use a clean, dry microfiber cloth or towel to dry the aluminum item. This step helps prevent water spots and streaks.
Step 9: Maintenance
To maintain the cleanliness of your aluminum items, regularly clean them using the above steps. Remember that some aluminum materials are coated or treated differently, so always check the manufacturer’s recommendations or guidelines for cleaning specific items.
