What is Aluminum
Light, durable and functional: these are the qualities that make aluminum one of the key engineering materials of our time. We can find aluminum in the homes we live in, in the automobiles we drive, in the trains and aeroplanes that take us across long distances, in the mobile phones and computers we use on a daily basis, in the shelves inside our fridges and in modern interior designs, but a mere 200 years ago very little was known about this metal.
Properties of Aluminum
Aluminum offers a rare combination of valuable properties. It is one of the lightest metals in the world: it’s almost three times lighter than iron but it’s also very strong, extremely flexible and corrosion resistant because its surface is always covered in an extremely thin and yet very strong layer of oxide film. It doesn’t magnetize, it’s a great electricity conductor and forms alloys with practically all other metals.
We can thank Aluminum for the changing image of modern cities and towns: the clarity of lines, the feverish desire to grow skyward, the beauty, functionality and environmental compatibility of present-day megalopolises. The glass faces of office skyscrapers are supported by lightweight and sturdy Aluminum frames. Entertainment, trade and exhibition centers literally rest on Aluminum frameworks. Stadiums, pools and other sports facilities are also built using Aluminum structures. This metal became one of the most popular materials among builders, architects and designers for the following reason.
25% of all aluminum produced worldwide is used in construction
Imagine that you have a light, but strong metal, which is not prone to corrosion, which is non-toxic and durable, and which can be given virtually any desired shape. Aluminum is a tool for unlimited creativity in the hands of the architect, making it possible to create structures that cannot be made from wood, plastic, or steel.
That is why it is so commonly used in modern construction.
