Is aluminum a metal | All you need to know

The silver-white metal Aluminum is, and in the periodic table the 13 elements. On the earth Aluminum is the most widespread metal one surprising fact about aluminum is, of the earth’s core mass making up more than 8%. And on our planet it’s the third most common chemical element after silicon and oxygen. At the same time, with other elements because it easily binds, in nature pure elements does not occur. That is the reason people learned about it relatively recently. In 1842 for the first time formally aluminum was produced and to earn to produce it on industrial scale formally aluminum was produced.

In nature is aluminum sulphates he most common form of aluminum found in nature. Tow sulphuric acids that combine theses are minerals; in these one is based on a alkaline metal and the other based on a metal form the third group of the periodic table.

For this day to clean water Aluminum sulphates are used, for cooking, in the chemical industry to this day to clean, in the chemical industry and in other sectors. By the way, from aluminum sulphates aluminum got its name which in Latin were called alumen.

About 300 various aluminum compounds to day we know about almost and contain aluminum form minerals, a key source mineral on Earth and a key source, to ruby.

A metal aluminum is definitely. In fact, in Earth’s crust it’s the most abundant metal. Not only for that, but Aluminum is also the second most abundant materials in after silicon in Earth’s crust.

Aluminum is metal?

At standard temperature and pressure, from a face-centered cubic crystals system bound aluminum atoms form by metallic bonding provided by the atoms outermost electrons. Hence, aluminum is also a metal.

A good aluminum is meta?

Because of it is Aluminum malleable and elastic than steel Aluminum is a very desirable metal. Aluminum can create shoes that steel cannot create it go places, often more intricate spinning’s and forming deeper. With deep and straight walls especially for parts, of choice aluminum is the materials.

To humans is aluminum poisonous:

To aluminum is inevitable and, perhaps human exposure, inestimable. Metal cation Aluminum’s free, Alaq (3+), it’s a highly biological reactive and the available aluminum biologic is non-essentially toxic.

Is it’s toxic to touch aluminum:

Not harmful exposure to aluminum, but serious health problems exposure to high levels can cause. To high levels of aluminums if you think you ha ben exposed, then you contact you doctor.

Properties of Aluminum:

Of valuable properties Aluminum offers a rare combination. In the world it is one of the lightest meats; then iron it’s three time lighter but the aluminum is also very strong, extremely flexible and corrosion resistant because in an extremely thin its surface is always covered and of oxide film yet very strong layer. Magnetize it does not, with practically all other metals it’s a great electricity conductor and forms alloy.

Aluminum annual demand;

Around 29 million tons per year worldwide demand for aluminum is. The economically and environmentally compelling the use of recycled aluminum is. To produce 1 tons it takes 14,000 kWh to produce of new aluminum. Of this to remelt conversely it takes only 5% and of aluminum recycle one tonne. Between virgin and recycled aluminum alloys there is one difference in quality.

Aluminum applications:

Soft, ductile, corrosion resistant pure aluminum is and a high electrical conductivity. For foil and conductors cables It is widely used, but for other applications the higher strengths needed with other elements is necessary to provide alloying. Of the lightest engineering metals aluminum is, to steel having a strength to weight ration.

Alloy Designations:

With copper, Zinc, magnesium, silicon, manganese and lithium Aluminum is most commonly alloyed. Of chromium, titanium, zirconium, lead, bismuth and nickel small additions are also made and in small quantities iron is invariably present.

With 50 in common use there are over 300 brought alloys. In the USA which originated by a four figure systems they are normally identified and is now universally accepted. TO use a five digit system cast alloy have similar designations.

Aluminum physical properties:

Density of Aluminum:

Around one third aluminum has a density that od steel and copper of the lightest commercially avaible metal making it. To weight ratio the resultant high strength makes for transport industries in particular makes it an important structural material allowing increased payloads.

Strength of Aluminum:

Have a high tensile strength Pure Aluminum does native. However, like manganese, silicon, copper and magnesium the addition of alloying elements.

Ro cold environment Aluminum is well suited. With decreasing temperature it’s tensile strength over steel in that it has the advantages with decreasing temperature its toughness while training. At low temperatures becomes brittle steel on the other hand.

Corrosion Resistance if Aluminum:

On the surface of aluminum a layer o aluminum oxides forms almost instantaneously, to air when exposed. To corrosion tis layer has excellent resistance. To the most acids it is fairly resistant but to alkali less resists.

Of Aluminum thermal conductivity:

Than that of thermal conductivity of Aluminum is about three times greater. For both three cooling and heating applications this makes aluminum important material such as heat- exchangers. I with its being non-toxic combines this property means aluminums is used extensively in cooking utensil as an kitchen ware.

Of aluminum Electrical conductivity:

For use as an electrical conductor aluminum has an electrical conductivity high enough for use, along with copper. Only around 62% of annealed copper although the conductivity of the commonly used conducting alloy (1350). The weight is only one third and as much electricity therefore conduct twice and of the same weight with copper when compared.

Aluminum Reflectivity:

From UV to infra-red, of radiant energy aluminum is an excellent reflector. It is widely  used in light fixtures it is widely used visible light reflectivity of around 80% means. As an insulting to protect against the sun’s rays in summer the same propertied of reflectivity make aluminum ideal, wile in winter insulting against heat loss.
