Alloys and Treatments

 

The alloys used by EXTRUAL for the manufacturing of the sections are adapted to meet the client requirements and the functionality planned for the final product. In this way, the most common are the following:

   ALLOY   APPLICATION
   6060   Architectonics
   6063   Architectonics
   6463   Decoration (high gloss)
   6106   Semi-structural
   6005 A   Structural
   6082   Structural

At the same time, the heat treatments applied to the sections vary depending on the mechanical characteristics to be achieved:

   TREATMENT   CHARACTERISTICS
T4 Press exit forced cooling and artificial ageing Low mechanical characteristics
T5 Press exit cooling and artificial ageing Normal mechanical characteristics
T6 Press exit forced cooling and natural ageing High mechanical characteristics
Intermediate between T4 and T5   Special characteristics (p.g.: Section forming)
