Physically, chemically and mechanically aluminium is a metal like steel,
brass, copper, zinc, lead or titanium. It can be melted, cast, formed and
machined much like these metals and it conducts electric current. In fact often
the same equipment and fabrication methods are used as for steel.
Light Weight
Aluminium is a very light metal with a specific weight of 2.7
g/cm3, about a third that of steel. For example, the use of aluminium
in vehicles reduces dead-weight and energy consumption while increasing load
capacity. Its strength can be adapted to the application required by modifying
the composition of its alloys.
Corrosion Resistance
Aluminium naturally generates a protective oxide coating and is highly
corrosion resistant. Different types of surface treatment such as anodising,
painting or lacquering can further improve this property. It is particularly
useful for applications where protection and conservation are required.
Electrical and Thermal Conductivity
Aluminium is an excellent heat and electricity conductor and in relation to
its weight is almost twice as good a conductor as copper. This has made
aluminium the most commonly used material in major power transmission lines.
Reflectivity
Aluminium is a good reflector of visible light as well as heat, and that
together with its low weight, makes it an ideal material for reflectors in, for
example, light fittings or rescue blankets.
Ductility
Aluminium is ductile and has a low melting point and density. In a molten
condition it can be processed in a number of ways. Its ductility allows products
of aluminium to be basically formed close to the end of the product’s
design.
Impermeable and Odourless
Aluminium foil, even when it is rolled to only 0.007 mm thickness, is still
completely impermeable and lets neither light aroma nor taste substances out.
Moreover, the metal itself is non-toxic and releases no aroma or taste
substances which makes it ideal for packaging sensitive products such as food or
pharmaceuticals.
Recyclability
Aluminium is 100 percent recyclable with no downgrading of its qualities. The
re-melting of aluminium requires little energy: only about 5 percent of the
energy required to produce the primary metal initially is needed in the
recycling process. |
Most commercial or industrial complexes use some sort of gate security system to protect the property when it is closed. The two metals that are used for making those gates are aluminium and iron. Aluminium gates are light, easy to install and gates made from iron provides more security and structural integrity. Thanks a lot.
