What’s known as both the ‘Green Metal’ and the ‘Metal of the Future’? - The answer is aluminium.

Aluminium is the material of choice for engineers, manufacturers and designers thanks to being - lightweight, durable, non-corrosive and eco-friendly (it is 100% recyclable). It can be combined into alloys to be even stronger.

It is the metal’s unique combination of light-weight and super-strength that makes it so well-suited for the critical parts used in automotive and aerospace.

Did you know?

Aluminium is driving the cars of today and tomorrow. From mass-market vehicles like the Ford F-150 to luxury cars like Audi, Mercedes Benz and Land Rover, Aluminium is increasingly the “material of choice” for automakers thanks to its strength and environmental advantages.1

Aluminium can provide weight savings of up to 50% compared with traditional steel body structures. This means that just 1kg of Aluminium in a car can eliminate up to 20kg of CO2 emissions over the vehicle’s lifetime.

With lower weight come better acceleration, better braking and better handling. All in all, Aluminium offers car makers the fastest, safest, most environmentally friendly and cost-effective way to increase performance, boost fuel economy and reduce emissions while maintaining or improving safety and durability.2

On December 17, 1903, Orville and Wilbur Wright made the world’s first human flight with their airplane, the Wright Flyer. They had carefully selected aluminium to cast the engine block and the cylinders combined with the wooden framework, an innovation at that time to maintain the weight as low as possible.3

The period between World War I and World War II (1918 - 1939) famously came to be known as the ‘Golden Age of Aviation’. It is said that at its peak (circa 1944), Americans were making around 11 aircrafts per hour, mostly from aluminium.4

Concorde was a supersonic marvel which could travel at Mach 2 speed. It was made possible by the ingenuity of the engineers to use aluminium for withstanding such harsh weather conditions and at the same time make it safer and economical to travel.5

Today, about 80% of a modern aircraft is made from Aluminium and its alloys. Aluminium checks all the boxes by offering a light-weight body, a rust-free durable frame, and high fuel efficiency.

Did you know?

Aluminium alloys are strong enough and light enough to be used in space structures and satellites. Aluminium was used for the outer shell of the International Space Station6 as well as for its window shutters, protecting the astronauts inside from impacts.

Aluminium was also the metal of choice for the Mars Orbiter Mission (MOM) or ‘Mangalyaan’ space probe which was launched in 2013 by the Indian Space Research Organisation, marking India’s first venture into interplanetary space.7

Power is a crucial part of modern-day life. It allows us to use electricity in home, such as lighting, heating and air conditioning, cooking, refrigeration, washing, television and computer usage.

It also provides energy for major industrial enterprises and essential everyday infrastructure.

Electricity is generated at large-scale power stations, mostly using heat energy from burning coal or wind energy or moving water.

Did you know?

Many of India’s long-distance trains are powered by electricity from overhead lines. Similarly, inner-city metro systems and suburban railways rely on electric power to operate. Approximately 85% of India’s freight and passenger traffic is carried by electric locomotives.8

Did you know?

Power is the fuel of the future for cars too. Electric cars have yet to take off in India but the government is targeting annual sales of 6-7 million hybrid and electric vehicles from 2020 onwards.9 India’s ambitious goals are part of plans to reduce pollution in major cities and cut the country’s dependence on oil.10

Iron ore

Iron ore is the main component of steel, which is the most widely used industrial metal and an industry that accounts for 98% of all global iron ore production.11

Due to its strength and availability, iron ore is used in a range of sectors including rail, roads, bridges, and buildings; aircraft, ships, vehicles and trains, engine components, electrical motors and power generators, surgical instruments and medicines.

Did you know?

The global steel industry uses two billion tonnes of iron ore per year,12 and a great example of steel in action is its use for continuous track, also known as caterpillar or tank track.

Originally invented in the 1800s13 and using iron ore as a key component, these steel tracks are used in place of wheels on industrial and military vehicles such as excavators, tractors and tanks to prevent them getting bogged down in muddy environments.

Did you know?

The vast majority of international trade is carried out by cargo ships, which transport a wide range of everyday items used at home and in the workplace. Without cargo ships, trade as we know it would be very different, and without iron ore, cargo ships as we know them would be very different.

The majority of ships hulls are made from steel plates, and iron ore is a key component of these steel plates, due to its durability, strength and weight.14 In fact, steel ships transport 90% of the world's cargo15, making iron ore indispensable to global commerce.

Copper is mankind’s oldest metal, dating back over 10,000 years16 and is as an excellent transmitter of heat and electricity. It is also resistant to corrosion and known for its ability to kill infections.

Copper is used in a wide range of industries, including electricity conductors, high voltage transmissions, micro-electronics, personal computers and electronic devices, aircraft components, trains and vehicles, solar energy panels and wind turbines; and for fighting copper deficiency in the human body and reducing infections.

Did you know?

Due to its excellent conductivity, one of copper’s main uses is electrical wiring. In today’s world we are always looking for alternative forms of power generation, and copper wiring is used extensively in wind turbines.

It forms a number of wind turbine components, including high-voltage power cables, transformer coils, rotor portions of the generator and also lighting conductors.17 Without copper, wind turbines would not exist in the form we know them.

Did you know?

Around 80% of infections are spread by touch18 and every day we come into contact with a range of surfaces, like door handles for example, often leaving infectious organisms on them. As a result, these surfaces are a direct contributor to the spread of bacteria.

Antimicrobial Copper is an alloy with copper as a key component that kills over 99.9% of bacteria within two hours of contact.19 Consequently, it is used in public spaces for items including handrails, push plates, hospital bedrails, light switches and taps20 to help prevent the spread of infection.

Zinc is the 4th most widely consumed metal in the world after iron, aluminium, and copper. Zinc is most commonly used is in the ‘galvanising’ process – when metal is coated with a layer of molten zinc to protect it from harsh environments.21

But Zinc’s uses are far more varied than you might think. We use it in medicines and X-Rays, railway tracks and bridges, even cosmetics and soaps, for fertilizers, and even in homes as luminous paints and fluorescent lighting.

Did you know?

Zinc is an essential nutritional mineral for humans and animals alike - after iron, it is the second most common trace metal found naturally in our bodies.

Zinc plays a fundamental role in gene expression, cell growth and cell reproduction. In Zinc Oxide form, you can find it in your sunscreens, soaps, and lotions helping to reduce sunburn and prevent the premature aging of your skin.22

Did you know?

Zinc is used in as a coating on iron and steel to protect against corrosion. Corrosion costs the US 3.2% of GDP annually - that’s around $425bn a year!23

It’s no wonder then that half of all Zinc produced today is used to galvanize steel to prevent against corrosion - it’s used for car bodies, street lamp posts, safety barriers and suspension bridges.24 Zinc makes the average automobile last longer—17 pounds of Zinc protects the car from rust, 20 pounds are used to make Zinc die-cast parts like door handles and locks, and each tyre contains about 1/2 pound of Zinc, needed to cure rubber.



Silver was one of the first metals to be discovered around 5000 BC and has been used for a variety of purposes ever since. The metal is obtained from silver mines or from lead and zinc mines where it is a by-product after smelting.

Silver is most commonly used for electrical applications and in electronics products because it is such an effective conductor of heat and electricity. It’s also used in coins, jewellery and even energy products like solar panels.

Did you know?

Silver has been used for its medicinal properties for thousands of years. Silver is germicidal and kills bacteria and other harmful organisms by absorbing oxygen. In World War I, before the widespread use of antibiotics, silver foil was wrapped around wounds to help them heal. Today, silver is used as an antibiotic coating in medical devices and equipment and is also part of the technology behind X-rays.25

Did you know?

One of the largest industrial uses for silver came from photography when in 1839 French artist Louis-Jacques-Mandé Daguerre developed the first practicable and publicly-available method of creating permanent images from a camera. His ‘daguerreotype’ process produced images on a silver-coated copper plate. Today, silver is still used in photography through the gelatin silver process, which is used to develop black-and-white films and printing paper.26

Crude oil does not only fuel cars and airplanes. Petroleum products and by-products have various, and often unexpected, uses in products that we use day to day.

Petrochemicals are used in all plastic products, in food additives (to increase shelf-life), and even in contact lenses (to make them soft and comfortable to wear).

Perfume, deodorants and antiperspirants commonly use propylene glycol, the petroleum-based material. Paraffin wax is also produced from petroleum and serves as a base ingredient for candles, crayons and lipsticks.27

Did you know?

Aspirin, the widespread medication used around the world to fight headaches and fever, is produced with benzene, a hydrocarbon that is typically derived from petroleum products.28

Did you know?

India is set to overtake China in energy consumption by 2040.29 The International Energy Agency estimates that India will be the fastest-growing crude oil consumer in the world through 2040, adding 6 million barrels a day of demand.

The IEA is not alone in its predictions regarding India. BP's Energy Outlook for 2035 30 and The Oxford Institute for Energy Studies31 also expect India to contribute to over half of the growth in world energy demand together with China, overtaking the latter towards the end of 2035.




Natural gas is a fossil fuel used as a source of energy for heating and electricity generation. It also serves as fuel for vehicles and as a chemical ingredient in the manufacture of plastics and other organic chemicals.32

Compressed natural gas (CNG) is widely used as a transportation fuel, by being burned in an internal combustion engine. Compared to gasoline, CNG vehicles emit far less carbon monoxide, nitrogen oxides, and particulates, playing a significant role in reducing environmental pollution.

Did you know?

A natural gas-powered Honda Civic delivers about a 15% less pollution compared with a conventional gasoline-powered Civic, while a gasoline-electric Civic hybrid is more cost-effective and delivers a 30% reduction in emissions.33
