Aluminium is a silvery-white metal that is abundantly present in earth’s crust. Its attributes and utilities make it one of the most useful materials known to man. Aluminium is tremendously versatile which has broad range of properties, chemical & mechanical compositions. An Aluminium alloy is an alloy in which Aluminium is the predominant metal. The alloying elements used most frequently by aluminium alloy manufacturers are magnesium, copper, silicon, zinc and manganese.

Aluminium and its alloys are used quite extensively in the production of engineering structures, transportation facilities and packaging. The various properties of aluminium that make it a superior metal are as follows:

Durability: Although these alloys tend to lose a bit of strength at tremendously high temperatures, their strength increases at sub-zero temperatures. This important property makes aluminium an extremely useful low-temperature alloy.

Corrosion resistant: Aluminium alloys also have a strong resistance to corrosion. This Property of aluminium is a result of its reactions to the atmosphere. This protective oxide skin that is created due to the atmosphere, shields it from weathering conditions, chemicals and acids.

Good electrical conductor: It is also an extremely good electrical conductor and is used more than copper even though the latter is a better conductor. This is because of its low density and its high cost efficiency. (https://www.azom.com/article.aspx?ArticleID=1446)

Malleable: Like gold, aluminium is an extremely malleable metal and can be cast into many forms. Aluminium can easily be rolled, forged, hammered and stamped into a variety of shapes. Aluminium can also have a wide variety of surface finishes and does not produce toxic fumes when burned at high temperatures. . (https://socratic.org/questions/why-are-metals-malleable)

Light weight: Aluminium is very light weight and has a low density. This makes it an excellent choice of material in the manufacturing of airplanes. It also makes aluminium easier and cheaper to ship and transport. . (http://transport.world-aluminium.org/modes/aircraft/)

Aluminium is 100% recyclable and recycled aluminium is identical to the virgin product. This makes it a much more cost-effective source material for production runs.

Because of its various utilities and abundant availability, recycling companies in UAE and scrap metals yard in Dubai have come to realize the immense value of this precious metal.
