Benefits and Drawbacks of Aluminum

by admin

Aluminum was found in the 19th century and has since become popular. Although it is the most common metal on earth, it is not always found in its purest form. Because of this, scientists had a difficult time separating it from other elements until the present process of extracting aluminium was created in 1886. Due to its small weight, it later developed into a prominent metal in the aerospace and aviation sectors. Today, aluminium is used in a wide range of products, such as high-rise construction, consumer electronics, trains, automobiles, home appliances, industrial equipment, and more. After providing a brief summary of this metal, let’s examine its benefits and drawbacks.

Benefits of aluminium

The following are some of the benefits of aluminium, which makes it the most commonly utilised metal in contemporary culture due to its advantageous physical characteristics.

It is compact.

The need for lightweight materials is rising as a result of the market demand for businesses to reduce CO2 (Carbon dioxide) emissions. Aluminum is a thin, light metal with a density of just 2.7 kilogrammes per cubic metre. It is utilised in sectors where weight reduction is essential as a result. It can be used in the aerospace sector to provide lightweight and high strength for flights that are under a lot of stress. Aluminum is utilised in the automobile sector to make lighter cars with better fuel economy.

Aluminum is pliable and adaptable.

Aluminum is strong and lightweight at the same time. It is the most flexible metal to work with as a result. Through a variety of processes, it is easily shaped to adopt the necessary shapes. Cutting, milling, drilling, bending, welding, and machining are all possible with aluminium. As a result, it is used in kitchen fitting and art. In addition, it is applied to the creation of futuristic products across all industries. Consider consumer electronics as an example. The nicest aspect about using aluminium to make complex designs is that it marries aesthetics with functionality. The same goes for this adaptable metal, which is utilised in a variety of applications including ships, trains, home appliances, and automobiles.

It is robust and resistant to corrosion.

Aluminum oxidation is responsible for the metal’s exceptional corrosion resistance. When the metal comes into contact with oxygen or any other oxidising source, it naturally generates a thin coating of oxidation. It is further protected from the outside air by this covering, which also prevents rusting.

High corrosion resistance has the advantage of extending the material’s life. Aluminum is quite durable, as was already said. Aluminum can also have its corrosion resistance strengthened, ensuring that it will endure for many years in industrial applications. Aluminum can also be anodized to further increase its overall corrosion resistance.

Aluminum may be recycled.

The interesting thing about aluminium is that there is no quality degradation while recycling. This means that it keeps its original characteristics and is completely recyclable. Additionally, recycling aluminium uses just around 5% of the energy required to produce a new one. This method lowers carbon emissions and saves money. Additionally, as the population grows, there is a surge in demand for aluminium items. The rising demand for aluminium cannot be met only by increased mining. Recycling fills the gap between supply and demand in this situation, maintaining continuing output.

It is a good heat and electrical conductor.

The material of choice for important power transmission lines is aluminium. Its superior heat and electrical conductivity is the cause. Aluminum has double the electrical current carrying capability of copper by weight even if its conductivity is only 60% that of copper by volume. This means that half of an aluminium wire will have the same electrical resistance as a copper wire. As a result, it is taking the place of copper with the extra advantage of being economical.

It is used in circuit breakers, connections, and electrical power cables. Additionally, aluminum’s strong conductivity has uses in heating and cooling systems. This metal is an effective heat and visible light reflector. As a result, aluminium roof coatings are utilised to lessen internal solar heat gain in homes. Last but not least, it is employed as a heat sink in a variety of products, including motherboards for computers, LED lights, and electrical goods.

Being impermeable, aluminium

You might have wrapped food with aluminium foil to take on trips. The impermeability of the material is the basis for the use since it protects the packed food from moisture, fumes, and volatile aromas. The thickness of the metal foil is precisely 0.007 mm. Additionally, it has no odour and is non-toxic, making it the ideal material for packing food and medications.

The drawbacks of aluminium

Even though aluminium has more advantages than disadvantages, those disadvantages are nevertheless important to consider. Here is a list of aluminum’s drawbacks.

It is more expensive than steel.

Aluminum is certainly less expensive than steel, but it can still be expensive. Similar to steel, aluminium can withstand tension. In light of this, designing the identical building out of aluminium rather than steel may result in higher project costs.

Aluminum welding is a challenging technique.

Despite all the advantages, welding aluminium is still a tiresome process. First off, compared to other metals, it has a lower melting point. As a result, the substance usually burns before melting. Second, because to its great thermal expansion, aluminium causes significant issues during the welding process. Aluminum is porous because it absorbs hydrogen while it is molten and leaves the bubbles behind when it cools to solid form. The oxides must be removed before welding can start because of its strong affinity for oxygen. Aluminum is difficult to deal with as a result of all these factors together.

More fragile than steel

Although steel comes out on top when considering solely strength, aluminium offers a good strength-to-weight ratio. Therefore, steel is chosen instead of aluminium for projects where weight is not an issue. A disadvantage of aluminum’s ductility and great malleability is that it makes constructions made of it susceptible to dents and scratches. Steel is now a more appealing option for projects that call for stronger buildings.
