Anodized aluminium: longevity, resistance and artistic impact
Anodized aluminium stands as a testament to innovation and durability. This electrochemically treated material undergoes a transformative process.
The final result enhances its resilience and introduces a spectrum of possibilities for a myriad of applications.
What is anodized aluminium?
An electrochemical process produces anodized aluminium. The metal is immersed in tanks. The magic unfolds as an anodic layer naturally grows from the aluminium itself.
It emerges as a material three times harder than its raw form. It is 60% lighter than competing metals like stainless steel and copper.
Anodizing aluminium parts is a meticulous process that goes beyond surface-level enhancements. Aluminium undergoes a remarkable transformation through the application of electrically conductive methods.
The result is an anodized coating that integrates with the metal substrate. Anodizing increases durability and corrosion resistance.
What is anodizing and how does it work?
Anodizing is part of electrolytic solutions. Chromic acid anodizing and sulfuric acid anodizing take centre stage.
These processes harness the power of electrolytes to induce controlled oxidation. They produce a layer of aluminium oxide that acts as a formidable shield against environmental elements.
Anodized aluminium is not just a surface treatment. It is a shield against the ravages of corrosion.
- The anodizing process begins by dipping aluminium into a special acid bath.
- Electricity flows through the liquid.
- Inside the bath, there is a cathode and the aluminium acts as the anode.
- The process releases oxygen ions.
- The ions then bond with the aluminium atoms on the surface of the part.
Anodizing carefully controls the oxidation of the metal, enhancing its natural properties in a controlled way. It significantly improves corrosion resistance.
This key benefit ensures longevity. This makes anodized aluminium a preferred choice in applications where durability is non-negotiable.
Aluminium, for example, maintains its ability to conduct electricity: it is perfect for different electrical parts. This combination of durability and conductivity makes anodized aluminium a leader in innovation.
Unlike other ferrous metals like iron, anodized aluminium is not limited by such factors. It is a versatile choice that goes beyond traditional limits. It offers a long-lasting option for many uses.
What is the difference between raw aluminium and anodized aluminium?
There are two main differences between raw aluminium and anodized one.
- Anodized aluminium is less reactive and more resistant.
- It finds its place in building materials, furniture, sporting goods, and more.
- Non-anodized aluminium is susceptible to environmental contaminants.
Anodized aluminium transcends its conventional role as a metal. It becomes a symbol of strength, versatility and aesthetic appeal.
- It remains strong and resilient, enduring through time and environments.
- It can adorn modern structures.
- It enhances consumer goods and provides the backbone for transportation.
Anodized aluminium has several important qualities.
- Corrosion Resistance. It is highly resistant to corrosion, making it durable in different environments.
- Hardness and durability. Anodizing makes aluminium three times tougher than before, reducing scratches and extending its life.
- Aesthetic versatility. You can colour anodized aluminium in many ways for different looks.
- Electrical insulation. It does not conduct electricity, which is useful for certain applications.
- Lightweight. Aluminium is naturally light, and anodized aluminium stays that way, great for things where weight matters.
- Thermal insulation. It can keep heat in or out, useful where temperature control matters.
- Environmental sustainability. Anodized aluminium is recyclable, and the process to make it is eco-friendly.
- Weather resistance. It can handle outdoor exposure well, enduring sunlight and moisture without much damage.
- Chemical stability. It stays stable when exposed to different chemicals, protecting it from corrosion.
- Adhesion qualities. The anodized layer sticks tightly to the aluminium, ensuring it will not chip or peel easily.

Anodized aluminium is used for outdoor stuff that needs to look good and last a really long time. It is an architectural element. We are talking about things like window frames and covers for buildings.
Expanded metal mesh with anodized steel is an element that reinforces the profile of a building. As we have seen, a good end product ensures longevity and impacts costs, significantly reducing maintenance interventions.
Architects and builders started using anodized aluminium in buildings outside back in the 1930s. Some of them are still standing strong after about 80 years and show that anodized aluminium can stand up really well against the weather.
Professionals who opt for anodized aluminium for buildings care a lot about it looking good for a long time. They want it to keep its original look for a really long time. With some care, it usually does.
Anodized expanded metal mesh
Good quality anodized aluminium can last a really long time. Scientists have even studied it by testing samples outside for up to 20 years.
For these reasons, anodized expanded metal mesh finds various applications in building facades and covers. Some common uses include:
- facades;
- sunshades;
- ventilation grilles;
- decorative screens;
- privacy screen;
- column covers;
- ceiling applications;
- balustrades;
- exterior art installations.
Anodized expanded metal mesh is employed in building facades to add a distinctive and aesthetically pleasing element. The anodized finish enhances the material’s appearance and provides corrosion resistance. It is suitable for long-lasting architectural applications.
The expanded metal mesh, when anodized, is an excellent solution for sunshades in building design. These elements contribute to the overall architectural style and offer shading solutions, controlling sunlight penetration.
