Light
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.
Strong
Its strength can be adapted to the application required by modifying the composition of its alloys. Mixed with small amount of other metal, it can provide the strength of steel, with only one-third of the weight. Aluminium alloys increase in strength without loss of ductility.
Long-lasting
All materials suffer degradation from weather conditions, corrosion and decay.
Aluminium’s natural ability to resist these influences better than many materials is one of its most widely appreciated features. The durability of aluminium applications, such as in building structures, clearly demonstrates this.
Very ductile
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.
Infinitely recyclable
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.
Excellent heat and electricity conductor
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.
Highly corrosion resistant
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.
Completely 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.
Good reflective properties
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.
———-ALUMINIUM IS A PART OF OUR DAILY LIFE———-
The material that offers intelligent solutions to our needs.
Beside us through a multitude of applications, aluminium accompanies us at every step of our life.
Since aluminium was first commercially produced over 115 years ago, its unique combination of properties has enabled designers and manufacturers to develop products that enhance the quality of life. Many applications in transport, medicine, food preservation and electricity distribution would not have been possible if a material with aluminium’s high strength-to-weight characteristic, outstanding barrier properties, good conductivity and corrosion resistance had not been available.
