subject: Why You Should Use Aluminium Over Steel [print this page] If someone were to ask you what you thought the most popular metal was, what would be your first reaction? For most people, they would probably say either steel or aluminium, and they would be correct. Both of these metals are being used in a number of applications across the world every single day. But is one of these materials better than the other? You need to watch who you ask this question to, as some people are going to be biased towards one or the other because they manufacturer it or work with it on a daily basis. There is, however, a strong argument for why aluminium is much more preferable to steel:
Aluminium is a highly lightweight material, making it perfectly suited to plenty of construction and building works. Steel, on the other hand, is two-thirds heavier, which makes it more difficult to work with.
Aluminium offers the same yield strength as steel, as well as offering the ability to be combined with a number of other substances, including: manganese, magnesium, silicon, copper and zinc. These combinations are aimed at increasing certain properties of the metal, such as strength, malleability or corrosion resistance.
Aluminium is, itself, highly resistant to corrosion; when used on the exterior of your home, it can become scratched and dented but will not begin to rust like steel does.
Aluminium retains its attractive sheen over time, whereas steel is known to very quickly lose its shine and colour, especially when exposed to the elements.
Aluminium has an electrical conductivity that is six times greater than that of steel, which makes it much more suited for use in applications that require an electrical current to pass through it.
Aluminium's crystal structure does not change when it is heated or cooled. Steel, on the other hand, is known to undergo dramatic crystal transformations at certain temperatures and to change its colour when heated.
Aluminium is the preferred material for cookware because of its fast heating capabilities and its cost effectiveness. In comparison to this, steel is the least preferred material, as it is a poor conductor of heat and doesn't distribute it evenly.
The next time you are given the choice between using aluminium and using steel for a particular application, remember the extensive list above and opt for the former material. There can be no denying that aluminium, as a material, is much more preferable to steel - it is much lighter and easier to work with; it is just as strong; it is resistant to corrosion; it stays attractive for long periods of time; and it has excellent electrical conductivity. Don't listen to those naysayers who promote the heavier material, steel, and go with your gut instincts.
