1. 4.3 Material Components/Definitions
   1. 4.3.1 Alloy Aluminumalloys are alloys in which aluminium is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, and zinc. Selecting the right alloy for a given application entails considerations of its tensile strength, density, ductility, formability, workability, weldability, and corrosion resistance. In aluminum profiles systems the most used alloys are 6060 and 6063.

   Table 4.3.1 Wrought aluminium alloy composition limits (% weight)

   Alloy	Si	Fe	Cu	Mn	Mg	Cr	Zn	Ti	Al
   6060	0.3-0.6	0.1-0.3	0.1	0.1	0.35–0.6	0.05	0.15	0.1	remainder
   6063	0.2-0.6	0.35	0.1	0.1	0.45–0.9	0.10	0.10	0.1	remainder

• 1. 4.3.4 Product finishes

  Anodizing is an electrochemical process of obtaining a protective or decorative coating on the surface of various alloys. Aluminium alloys are anodized to increase corrosion resistance, to increase surface hardness, and to allow dyeing (coloring), improved lubrication, or improved adhesion. The anodic layer is non-conductive.

  Painting (polyamide powder painting) is powdered composition based on polymer, curing agent, pigment, fillers and some other special components. It is applied for a painting of aluminum profiles. The thickness of the layer is several microns.

  Wood Effect is the process of applying a wood grain effect onto aluminium. Currently, it is considered the best product on the market for wood decoration.
