Aluminum alloys utilized
The extrusions manufactured by Profall are made with so-called soft alloys: these are essentially the alloys that belong to the 1000, 3000 and 6000 series.
Alloys of the 1000 series
In terms of aluminum content, alloys of the 1000 series have a minimum purity rating of 99.5%. This gives them a high capacity in terms of electrical and thermal conductivity. Furthermore, they are also extremely resistant to corrosion. They are typically utilised in the electrical and electromechanical industries.
Alloys of the 3000 series
Alloys of the 3000 series, which are mainly comprised of manganese, offer even greater resistance to corrosion, and are generally utilised for braze welding purposes. Products made using alloys of the 3000 series are typically utilised for heat exchangers and automotive applications.
Alloys of the 6000 series
Alloys of the 6000 series, on the other hand, contain Silicium and Magnesium. This family of soft alloys is characterised by its ease of processing and welding. In fact, these alloys are commonly used to manufacture welded structures and machined components. They are used to manufacture the majority of all specially-designed extrusions for industrial uses. This family includes one of the most used alloys in the extrusion industry: 6063 aluminum, widely employed to manufacature aluminum bars and tubing.
Profall utilizes a wide range of aluminum alloys: 1050 – 1070 – 3003 – 3103 – 3004 – 6060 – 6063 – 6005.
