Aluminium

Aluminium is an incredibly light metal, strong and relatively cheap to manufacture.

Used on cars, in cans, and other objects where heavier metal would cause ‘dead weight’ – increasing fuel consumption or transportation costs, its alloys can be modified to adapt its strength.

Aluminium is also an excellent conductor, making it the ideal choice for masts and other products that would collapse under the weight of the materials above it, and is hardwearing enough that it doesn’t rust, or ablate when exposed to the elements. Or at least it doesn’t rust in the traditional fashion of other metals. It’s even used in power transit, and forms part of the transmission wires from pylon to pylon.

Rust free?

Aluminium oxidises into a thick coating, protecting the metal underneath, without rotting or deteriorating – its oxidised upper coating is often one of its best features when used to coat the exterior of buildings in panels. Painting or lacquering or otherwise sealing the surface can help with its corrosion resistance, making it an ideal product for sidings or cladding panels.

It’s also an ideal reflective material of both heat and light, so it can be used in light fittings, rescue blankets or even tinfoil. Even at foil thickness (0.007mm) it’s completely impermeable, has no aroma and doesn’t transfer any metal taint to the food inside it, but it’s still a great heat conductor. It’s an ideal packaging for food, pharmaceuticals and other sensitive products.

Recyclable too

Aluminium is 100% recyclable and doesn’t downgrade or deteriorate on recycling. The reconstitution and melting process to recycle aluminium is about 95% more efficient than its initial creation, meaning that it’s possible to recycle aluminium for a fraction of its original production cost. Unlike other metals that may either need the addition or subtraction of components on recycling, aluminium can be recycled again and again without loss of properties or penalty.

Background

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.
