Industrial fields where anodized aluminum products find applications
Aluminum profiles resulting from anodizing are mainly used for a great variety of applications concerning the fields of furnishings – even the technical ones – and constructions.
Specifically, they are used as:
- doors and windows in houses and offices
- fixtures and blinds
- terraces, gates, doorways, shutters
- railings, banisters, handrails
- canopies and shelters
Nevertheless, in order to be even more specific, anodized aluminum products are required in multiple industrial fields, thanks to their natural qualities. In fact, they are suitable for installation in uses concerning the following sectors:
- Transports, where they are used as components for the assembly of vehicle chassis, windows, interiors, and exteriors of vehicles
- Furnishings, because our anodized aluminum products are renowned both in the home and contract furnishing fields
- Technical furnishing elements, thus used in offices, shops, public places, and expositions
- Lighting, where they serve as components for domestic and industrial lighting
- Electronics, where our anodized aluminum products can be used for heat sinks for photovoltaic panels. inverters, computers, and peripheral devices
- Electromechanical, used with terminal elements and electrical transformer coils as a replacement for copper
- Automotive, where they serve as components for heat exchangers and air-conditioning systems, radiators, pipes, and fittings for fluid distribution applications
- Aerospace and aircraft, as a finishing product in beams and keels, cockpits, landing gears, fuselages, and fuel tanks
The aluminum alloys used in anodizing
Our anodized products are made from specific aluminum alloys, those that better adapt to the type and configuration of the extrusion:
- the anodized aluminum products of the 1000 series offer a degree of purity of 99.5%, are excellent electrical and thermal conductors, and perfectly resist corrosion
- the anodized aluminum products of the 3000 series, instead, are composed of manganese, an element that gives high resistance to corrosion and compatibility with braze-welding treatments
- finally, the 6000 series is composed of aluminum, silicon, and magnesium, which makes the anodized products easier to treat and weld
In particular, this last series includes aluminum 6060, one of the most employed alloys in the manufacturing of anodized products. Aluminum 6060, in fact, offers innate properties such as:
- resistance to corrosion
- easy workability
- thermal and acoustic insulation
- suitability with welding

How we manufacture our anodized aluminum products
As we have mentioned earlier, anodizing is an electrochemical process that allows the formation of a protective or decorative oxide layer on the surface of an aluminum product. The result is an extrusion with improved technical, mechanical, and aesthetic properties.
Aluminum products anodizing, as well as other surface treatments, is carried out inside systems where the aluminum profile is immersed into a sulfuric acid bath and, thanks to the electrolytic process, they give life to an oxide layer that covers the material and gives it better resistance to corrosion and external agents.
The thickness of the layer and the processing times depend on the application needs of the anodized aluminum product. Thus, they can vary considerably according to the requirements.
Let’s take a closer look at the advantages and disadvantages of using anodized aluminum products.
The advantages of anodized aluminum products
Anodized aluminum products find widespread use in various industries thanks to their advantages:
- they are corrosion resistant: once they undergo the anodizing, in fact, aluminum products improve their natural characteristics and become even more resistant
- they have a very porous surface – thus anodizing is used as a treatment necessary for painting: anodized aluminum products better retain paint and make the color more permanent
- they are long-lasting because they’re robust and use-resistant, thanks to the new qualities that anodizing gives to the aluminum product
- they are completely recyclable
The disadvantages
Do anodized aluminum products also have cons? It’s fair to ask. Actually, from a mechanical point of view, anodized aluminum doesn’t have any disadvantages. Nevertheless, if it’s not properly treated, it can show stains and flaws on the surface.
The accuracy that must be put during the treatment steps is fundamental to obtain extrusions that, as well as offering advantages in terms of resistance and durability, are also aesthetically pleasing.
Colored anodized aluminum profiles
Among the services we offer, there is also painting. Anodized aluminum, in fact, can be manufactured with endless matt or polished colors, from black to white and gold.
Once anodized, the aluminum products are washed through advanced brushing techniques that remove any impurities in order to meet every requirement in terms of color and shine.
The coloring process, carried out with powder coating, consists in filling the pores on the oxide layer with a RAL color – which is resistant to light. These colors are then sealed through fixing.
Basically, painting allows for maintaining all the advantages of anodized aluminum products while offering a color range that can meet any aesthetic need.
