Facts of ALUMINIUM VS ALUMINUM You Need To Know

Aluminum or Aluminium is the most abundant element in the earth’s crust, making up about 8% of the surface. Aluminum and Aluminium are the two names for element number 13 in the periodic table, and aluminum is a lightweight metal. It is an excellent conductor of heat and provides an extraordinary appearance to make attractive products. Aluminum has a wide range of applications in various industries.

What’s the difference between ALUMINIUM VS ALUMINUM?

Aluminum is a metal with many beneficial properties and practical applications, but it has a somewhat complicated naming history in the scientific community. The legacy of this confusion is the multiple spelling options still commonly used throughout the English-speaking world.

What are the origins of the two names?

In 1808, Sir Humphry Davy identified the presence of the metal in alum, which he first named “aluminum” and later “alumium.”

He also discovered and named sodium, potassium, calcium and magnesium, barium, and boron; these names have many uses of “ium.”

In 1812, Davy introduced the name “aluminum” in his book Elements of Chemical Philosophy, although he had previously used “aluminium.” Adopted the formal name “aluminium”  to match most other elements’ “-ium” name. So, the use of “ium” is seen as more dominant in the UK and other parts of the world. However, for Americans, the metal in everyday use is still referred to in writing as “aluminum.” Today, we can use both versions interchangeably and with the same meaning.

 

What are aluminum and bauxite?

Aluminum is the third most common chemical element in the earth’s crust, and it exists in the form of oxides and aluminum silicates. The ore bauxite is the raw material for the production of aluminum.

Aluminum and its alloys’ main applications in automotive manufacturing, the construction industry, mechanical engineering, and packaging.

How is aluminum produced?

It was first discovered in 1808. However, it was not until 1886 that the electrolytic process was invented, making the metal economical to produce.

Bauxite, an ore containing up to 60 percent aluminum, is the only economically important raw material used in its production. In the Bayer process, the mined ore is heated in a pressure vessel at 150 to 200°C together with caustic soda. The aluminum is dissolved into sodium aluminate during the extraction process. The iron-rich residue, red mud, is filtered out. This corrosive substance must be stored as toxic waste. In the electrolysis process, which uses large amounts of electricity, the alumina is melted and reduced to metallic aluminum: the production of 1 million tons of alumina uses the same amount of energy as 500,000 households per year.

Why do aluminum profiles generally need surface treatment?

Without surface treatment, the appearance of aluminum profiles is not beautiful, and they are easy to be corroded in humid air, so it is difficult to meet the requirements for high decorative and strong weather resistance of aluminum profiles in construction materials. In order to improve the decorative effect, enhance corrosion resistance and prolong the service life, aluminum profiles are generally subject to surface treatment.

What are the advantages of using aluminum?

  • Good strength-to-weight ratio
  • Cost-effective production
  • Corrosion resistant, high electrical and thermal conductivity
  • Complex, intricate shapes are possible
  • Attractive appearance
  • Flexible and highly reflective,easy to manufacture
  • Precise, close tolerances, freedom of design

Is aluminium a recyclable material?

Aluminium is 100% recyclable and can retain its properties indefinitely, so it can use to produce new packaging solutions or applications. Due to its properties, more than 75% of the aluminium once produced is still in use in production today. Recycling aluminum saves a lot of energy and reduces CO2 emissions.

Why Is Aluminum Often Used As A Material In The Manufacturing of The Automotive Industry?

1) Lightweight.

For every 1% reduction in overall vehicle mass, fuel consumption can be saved by 0.6%~1.0%; for every 100 kg weight reduction of a car, CO2 emissions can be reduced by about 5 g/km, and for every 1 kg of aluminum used in a car, exhaust emissions can be reduced by 20 kg during its service life; automobile exhaust emissions are positively correlated with fuel consumption; existing cars are becoming more and more advanced and can use more equipment. Also makes the use of lightweight aluminum inevitable.

2) Main objects of automotive light-weighting.

The engine, chassis, body, and interior and exterior trim account for a large proportion of the car’s total mass, and the potential for weight reduction is excellent. The body is a more significant component of the car’s weight, accounting for about 30% of the car’s total weight, so the body of aluminum is pivotal.

Main objects of automotive light-weighting.

3)Highly recyclable

Aluminum is good for the environment because it is highly recyclable and consumes less energy than raw materials to produce aluminum from scrap. The weight reduction of cars also reduces carbon dioxide emissions, significantly reducing environmental pollution and improving environmental quality.

4)Improve driving performance and safety

Reducing the weight of the vehicle can improve the driving performance of the vehicle. The vehicle is more stable, the passenger space is more extensive, and the aluminum alloy structure can absorb and disperse more energy when impacted, making it more comfortable and safe.
