Aluminium: The Many Lives of an Ever More Valuable Metal
Aluminium is a ductile, lightweight metal with its distinctive silvery-white appearance. It is an excellent conductor of heat and electricity, highly reflective, and almost infinitely recyclable without losing any of its original properties. Around 75% of all the aluminium produced since the late nineteenth century is still in use today, although often in forms completely different from those in which it was originally manufactured.
Naturally occurring in the Earth’s crust, where it accounts for approximately 8% of its composition, aluminium is the most abundant metal on the planet. Today, it is also the second most widely used metal in the world after steel. Since its industrial-scale introduction in the late 1800s, global demand has grown rapidly, reaching around 29 million tonnes per year, of which approximately 22 million tonnes come from primary aluminium and 7 million tonnes from recycled scrap.
Thanks to its exceptional combination of properties – light weight, strength, versatility, and a strength-to-weight ratio superior to that of steel – aluminium has become a symbol of modern industry and a leading material across countless sectors.
Recycling aluminium requires approximately 95% less energy than producing primary aluminium from bauxite. For this reason, it is often described as an “energy bank”, capable of preserving its value through an unlimited number of life cycles.
A Truly Universal Metal: Aluminium Is Everywhere Around Us
Aluminium is extensively used in the energy sector, architectural systems and construction, automotive manufacturing, aerospace and marine industries, food packaging, electronics and related technologies, as well as e-mobility and modern transportation systems.
In the aerospace industry, its outstanding strength-to-weight ratio has revolutionised aircraft design. In the automotive sector, aluminium helps reduce vehicle weight, improving efficiency, lowering fuel consumption, and extending the driving range of electric vehicles. In construction, it makes it possible to create elegant, lightweight, and durable structures with increasingly slim, minimalist profiles. Within the window and door industry, aluminium enables the production of sleek yet highly resistant framing systems.
Modern technology also relies heavily on aluminium. Smartphones, laptops, tablets, and computers frequently use aluminium housings and components not only for their premium appearance but, above all, for their excellent thermal conductivity, which efficiently dissipates heat away from sensitive electronic components.
In the energy and electrical infrastructure sectors, aluminium’s low weight and excellent electrical conductivity make it the preferred material for high-voltage transmission lines, electrical systems, and renewable energy technologies. Many support structures for photovoltaic installations and components used in wind turbines are manufactured from aluminium.
Alongside these highly technological applications, aluminium also plays a quiet yet essential role in everyday life through food packaging. Beverage cans, trays, pharmaceutical blister packs, foils, and containers rely on aluminium’s ability to protect products from light, air, moisture, and bacterial contamination, preserving their quality and nutritional value without affecting taste or aroma – even at extremely thin gauges of just 0.007 mm.
Characteristics, Properties and Advantages of Aluminium
Aluminium owes its outstanding performance to a combination of technical properties that is virtually unmatched.
Corrosion Resistance. When exposed to air and moisture, aluminium naturally forms an extremely thin oxide layer that protects it against atmospheric agents, particularly in industrial environments. Surface treatments such as anodizing – an electrochemical process that creates a protective, porous layer of aluminium oxide – can further enhance this protection while also improving the material’s aesthetic appeal.
Thermal and Electrical Conductivity. Aluminium’s thermal conductivity is approximately 50–60% that of copper, making it an excellent choice for cookware and heat exchangers used in the chemical, food-processing, and aerospace industries. In terms of electrical conductivity, it reaches around 62% of the International Annealed Copper Standard (IACS) while weighing only about one-third as much as copper.
Reflectivity. Smooth aluminium surfaces reflect approximately 80% of visible light and up to 90% of radiant heat, making the material valuable not only for its visual appeal but also for technical applications such as roofing systems and thermal shielding.
Non-Toxicity. Aluminium is safe for direct contact with food, which is why it is widely used in cookware and food packaging without posing any health risks.
Recyclability. As mentioned earlier, aluminium is one of the most recyclable materials available. Recycled aluminium retains virtually all the properties of primary aluminium while requiring only around 5% of the energy needed for primary production. Today, approximately 60% of aluminium reaches end-of-life recovery, with Italy standing out as one of Europe’s leading performers. The country achieves a 69.5% recycling rate for aluminium packaging and an overall recovery rate of 72.9%. Beverage cans perform even better, reaching an impressive 92.8% recycling rate, well above the European average of 76.3% and already exceeding the targets set by the European Union for 2030.
Mechanical Strength. Pure aluminium has a tensile strength of approximately 90 MPa, but this can be significantly increased through processes such as cold rolling or by creating alloys with elements including copper, manganese, and silicon, which can be further strengthened through heat treatment.
Excellent Strength-to-Weight Ratio. This is one of aluminium’s greatest advantages. It allows manufacturers to create lightweight yet extremely strong structures, making it ideal for transportation applications such as cars, ships, and aircraft.
Ease of Processing. Aluminium can be rolled, stamped, extruded, or machined at high speed with remarkable efficiency. This ease of fabrication also contributes to lower manufacturing costs.
Ductility and Malleability. Aluminium can be drawn into fine wires and shaped with exceptional ease. In its molten state, it is extraordinarily versatile and can be transformed into a vast range of products, including sheets, tubes, and bars. From ultra-thin food foil to structural beams supporting entire buildings, aluminium demonstrates remarkable adaptability.
Performance at Low Temperatures. Unlike many other metals, aluminium does not become brittle in cold environments. On the contrary, its mechanical strength and corrosion resistance actually improve, making it particularly suitable for demanding low-temperature applications.
Impermeability and Neutrality. Even in extremely thin gauges, aluminium provides an effective barrier against moisture while preserving the taste and aroma of packaged products, making it indispensable in the food packaging industry.
Non-Magnetic Properties. Aluminium is not attracted by magnetic fields, making it suitable for a wide range of electronic applications and electromagnetic shielding.
Sound and Impact Absorption. Particularly when produced in foam or porous forms, aluminium offers excellent sound-absorbing properties, making it valuable in both construction and the automotive industry for reducing noise and vibration.
Surface Finishes. In many applications aluminium requires no additional protective coatings. When desired, however, it can be enhanced through brushing, shot blasting, powder coating, or electrochemical treatments such as anodising, offering virtually unlimited aesthetic possibilities.
Primary Aluminium vs Recycled Aluminium: The State of the Art
Today, the distinction between primary aluminium and recycled aluminium has become increasingly important. Primary aluminium is produced directly from bauxite through highly energy-intensive industrial processes. Recycled aluminium, on the other hand, is obtained by remelting scrap metal, production offcuts, old window frames, beverage cans, and other aluminium components.
From a technical perspective, recycled aluminium can achieve performance levels that are extremely close to those of primary aluminium. Any differences mainly depend on the quality of alloy separation and the control of residual impurities. However, advances in sorting and refining technologies are making recycled aluminium increasingly high-performing, to the point that it has already become the standard production material across many industrial sectors.
The future of aluminium is closely linked to circular economy models and closed-loop supply chains, in which production waste is continuously transformed into new raw material without losing value. Advanced sorting systems and increasingly sophisticated recycling technologies will make it possible to produce materials that are even more consistent, sustainable, and efficient in the years ahead.
Aluminium Alloys for Windows, Doors and Architecture
From a mechanical standpoint, pure aluminium is too soft for many structural applications. This is why it is alloyed with elements such as magnesium and silicon, creating the well-known 6000 series alloys, which are widely used in the architectural and window manufacturing industries.
6060 Alloy (AlMgSi)
The 6060 alloy is the benchmark material for architectural aluminium profiles. It is highly valued for its excellent extrudability, allowing manufacturers to produce complex, slim, and elegant profiles, while also delivering outstanding results with surface treatments such as anodising and powder coating.
6063 Alloy
Very similar to 6060, the 6063 alloy offers slightly higher tensile strength and hardness. It is often preferred for larger structures or whenever flawless aesthetics after finishing are a priority.
6082 Alloy
Although less common for standard architectural profiles, 6082 alloy is widely used for structural components and large window or door systems requiring even greater mechanical strength.
These alloys combine exceptional dimensional precision with outstanding mechanical performance and premium-quality surface finishes, offering several key advantages.
Minimalist Design
Thanks to the high strength of 6060 alloy, manufacturers can produce exceptionally slim profiles for windows, doors, and curtain walls, maximising glazed surfaces and natural light while meeting contemporary architectural trends.
Virtually Maintenance-Free
Aluminium naturally develops a protective oxide layer that makes it highly resistant to rust and even the most aggressive weather conditions.
Complete Sustainability
At the end of their service life, aluminium profiles are 100% recyclable, delivering significant energy savings compared with producing new primary aluminium.
Unlimited Aesthetic Possibilities
Thanks to epoxy powder coating, aluminium profiles can be finished in virtually any colour, shade, texture, or visual effect while maintaining excellent durability and long-term performance.
Powder Coating: Protection Meets Aesthetics
Surface treatment technology for aluminium has reached exceptionally high standards. Epoxy powder coating, now widely adopted across the industry, offers numerous advantages over traditional liquid coating systems. From an aesthetic perspective, it produces a smooth, uniform finish free from imperfections or inconsistencies, giving products a premium, professional appearance while also reducing environmental impact.
Before powder coating, aluminium undergoes a critical surface pre-treatment process, which typically includes degreasing, rinsing, phosphating, or advanced nanotechnology treatments. This is the most crucial stage of the entire coating process, as it largely determines the final quality of the finished product.
Proper pre-treatment:
- improves paint adhesion to the substrate;
- increases resistance to corrosion, moisture, and chemical agents;
- ensures a clean, activated, and uniform surface;
- reduces coating defects such as peeling, blistering, and delamination.
This sophisticated manufacturing process has evolved steadily over the years. Today, aluminium is an extraordinarily versatile material capable of replacing far more expensive and difficult-to-handle alloys in both manufacturing and transportation.
From ultra-thin household aluminium foil to contemporary architectural masterpieces, from aluminium colour sample collections to advanced industrial components, aluminium continues to demonstrate an unmatched ability to adapt to the needs of both the present and the future. It is a modern, elegant, technologically advanced, and sustainable material—a metal that continues to reinvent itself in countless new ways.
