How the humble (aluminium) 'can' changed the world!

The humble Aluminium can. What's so special about the ubiquitous can? We start our story with a simple question asked in the 18th century for a very complex problem at that time.

The year is 1795. Napoleon declares 12,000 Francs to anyone who can devise a way of preserving food for his army & navy. For millennia, it had baffled even champion strategists and generals on how to feed the troops during a war. How does one supply (fresh) food to thousands of men across several inaccessible locations of battle without requiring to replenish the stock again and again? Stripping small towns and villages of its resources was not always a reliable option. So what could be a viable solution then?

For 15 years, the money went unrewarded… until confectioner Nicolas François Appert claimed the prize in 1809. He experimented on the preservation of fruit in sugar jellies by sealing them in glass jars and heating them for varying lengths of time. But he could only claim the prize on the only condition that the French government put before him - he might publish his theory but not patent it. He became a darling of the media instantly, and was titled as the ‘Father of Canning’.

But there was a problem. Appert’s glass bottles were not durable at all. Sometimes, they simply exploded due to high internal pressure. Imagine stocking food in glass grenades in the inventory during the war! A few years later, Phillipe de Girard invented the ‘tin can’ whose upgraded versions we see today.

As the years rolled by,
  • 1813: John Hall and Bryan Donkin opened the first commercial canning factory in England
  • 1818: Peter Durand introduces his tinplated iron can in America.
  • 1819: Thomas Kensett and Ezra Gagett start selling their products in canned tinplate cans.

This was just the beginning of a revolutionary movement in the human history which altered the way food and beverages would be consumed in the future. In 1935, the first beer can was introduced. Named “Krueger Cream Ale”, it was sold by the Kruger Brewing Company of Richmond, Virginia. This was followed by canning carbonated soft drinks in 1940.

In 1941, more than 140 years after Napoleon’s quest began for quelling his troops’ hunger, the US soldiers rely on canned field rations during WWII. Two years later, Lyle Goodhue and William Sullivan invented a portable aerosol can using pressurized gas that could be used by US servicemen to kill disease-spreading insects during WWII.

Until now, tin, iron & steel were the primary materials used in canning. The problem with this arose when the taste and the composition of the internal contents changed over time as it reacted with the metal. So, it became a necessity to find an alternative which could hold all the quality of the contents intact and be extremely durable at the same time. The solution lay in using Aluminium.

It was in the 1950s, the Coors Brewing Co. found out that the taste of their beer drastically changed in the tin-lined steel container. Also, it was too expensive to buy newer cans over and over again. Coors President Bill Coors became interested in aluminium as a better container — beer chills quicker in aluminium, it’s light and less expensive to transport, and it doesn’t alter the taste. Also, aluminium is 100% recyclable. Aluminium cans are recycled over and over again in a true ‘closed loop’ recycling process. Glass and plastic are typically 'down-cycled' into products like carpet fibre or landfill liner.

Aluminium was introduced in the metal can-making in 1957 and two years later, the first all-aluminium beer can was introduced by Ermal Fraze (Kettering, Ohio) who invented the easy-open can! Bill put Coors beer in a 7-ounce, two-piece recyclable aluminium can.

There has been no looking back since.

By 1985, Aluminium cans had taken over the beverage packaging market. Astronauts in outer space receive carbonated beverages in cans. Companies like Coca-Cola, Anheuser-Busch use it extensively to sell their products, lending them longevity, intact quality and massive cost-effectiveness.

As we start looking for viable and inexpensive solutions to share fresh food items across the world, aluminium will always be the most preferred material due to its inherent characteristics. The humble (aluminium) can’s story is nothing short of incredible as it made our life vastly convenient today.

The choice is clear - Aluminium body for high end smartphones

A lot of phone companies are trying to build slim and sturdy phones for the ever growing market of steroid enhanced hardware capabilities. With phone manufacturers stuffing more RAM and precision cameras in the modern phones, the weight and robustness of the frames becomes all the more important. Today, some manufactures prefer a fiber body to reduce the overall weight in comparison to metal bodies. However, there’s something which still draws a larger advocacy of using aluminium bodies instead of a plastic or fiber. In 2007, Apple CEO Steve Jobs penned an open letter highlighting changes to the company's environmental policy in hopes of achieving "a greener Apple." In the letter, Jobs specifically noted the Mac maker's adoption of aircraft-grade aluminum in order to improve recycling uptake. Apart from the cost reduction implications, Apple is strongly in favor of aluminium usage in all its products for improving its year on year recycling capabilities with

Nespresso gives a Second Life to its signature aluminum coffee capsule

“Science may never come up with a better office communication system than a coffee break” – Earl Wilson A cup of coffee is a moment of pleasure. Everyone loves a good cup of coffee. Some even go to the extent of brewing that perfect cup of coffee for themselves because they know coffee taken in any other configuration might just ruin their happiness.

Aluminium in guitars – It's all music to our ears

Think of a guitar and the classic wooden version comes to mind. There are hundreds of types and they come in all shapes and sizes. Some passionate players even go for custom made guitars just to suit their movements and taste. The simple guitar is still evolving with newer uses of the instruments in concerts and other forms of music. The use of wood in the body and the neck of a guitar is not going to cease in a long time. However, the use of other selected materials by modern guitar manufacturers has significantly improved the sound quality and handling of the guitars. “Manufacturers were making custom guitars from solid billeted aluminum. I was still in graduate school and couldn’t afford such instruments. So I decided to make a competitively priced guitar. Instead of wood or plastic, I opted to use 0.080-in. aircraft-grade aluminum sheet metal because of its quality and durability,” says the then-future CEO of Normandy Guitars.

Aluminium extrusions - The ultimate value addition of Aluminium downstream

From simple paper clips to complex pieces used in advanced technology, aluminium extrusions are created in various shapes and sizes for value added end use utilizations. The computer you are using right now contains at least one aluminium profile in the form of a heat sink. This takes advantage of aluminium’s excellent thermal conductivity, unique anodising capability and freedom of design to keep your computer’s processor cool. Different cross sections of extrusions Extrusion is a process used to create objects of a fixed cross-sectional profile. A special tool called a ‘die’ is used to create these extrusions by cutting or shaping the material with the help of a press. These dies are customized to create the wanted design. The process involves the pressing of a pre-heated solid cylinder of aluminium (billet) which is forced through the die opening. The billets are heated to a temperature range of 350 – 500 degrees Celsius. Aluminium does not glow when heated ye

Lamborghini's raging Super SUV URUS - a balance of power and weight

This is unlike any Lamborghini automobile ever! An SUV from the company who produces supercars made from the blood of raging bulls?
