Check out Aluminum's history and its reputation before buying....
Aluminum might be a common metal now, but was once rare and the most valuable in the world. This was before the industrial process called Hall-Heroult was invented at the close of the 19th century. Before 1880s, aluminum was as valuable as gold and as expensive as silver. Napoleon was known to have given a banquet using aluminum utensils to the important guests while gold utensils were given to common people.

Indeed, the story presents the rarity of aluminum in the past. It was almost impossible to find aluminum in pure deposits. With its first production in 1825 in an impure form, all at once, Danish Physicist and chemist Hans Christian knew that mankind will benefit from it. Continuous research had paid off, more than 75 years after, aluminum was born. Today, it is one of the most useful metals known to man.
Currently, there are two accepted names to refer to this metal. One is aluminum and the other is aluminium. Aluminium was first recognized in 1990, while aluminum came three years after. Aluminum is widely known when referring to this alloy used in the industrial sector. It occurs everywhere, in any kind of environment and in commerce.
Used in almost everything, aluminum has become an apparent part of man’s day to day living. Aluminum, compared to other elements is non- toxic. It has a low density, and has a very strong resistance to corrosion. It has become one of the most in demand material in the aerospace industry. In structural materials, aluminum is usually in the form of aluminum bars, mostly round bars, rectangular, square-shaped aluminum bars. Aluminum rods and aluminum wire products are also widespread and in use almost anywhere around the globe.
Aluminum in aluminum bars have passed through series of developmental research. The different variety of aluminum bar alloys comes as a result of its components. Research in engineering involving aluminum bars become expensive as lack of assessment on this aspect has led to series of structural failure. Improperly designed structures have declined aluminum use at a certain point. Later years had graced aluminum a bounce back in structural industry.
These days, engineers, when using aluminum bars know that it is designed for a certain time frame and not for infinity; unlike some structures that has withstood the test of time. Unlike steel which has a well-defined fatigue limit, aluminum are expected to crash over a period of time.
Another important property of aluminum seen in most aluminum bars today is their sensitivity to heat. The problem with aluminum alloy in some aluminum bars is that they can be close to burning without showing any visual signs. Most aluminum alloys do not turn red before burning.
To be more than fitting, some aluminum bars at present undergo a process called annealing to increase its ductility and make it workable. In structural engineering, annealing means heating the material to soften its parts and cooling it down right after, with still air or water, to improve its cold working properties. This process makes aluminum bars more appropriate for structural works. Aluminum would be grateful to technology in giving the alloy a chance to prove its usefulness in just about anything structural.
As for its other uses, aluminum is under scrutiny, as claims are rising that the element is bad for health.
