When aluminum that is to be used as an extrusion is combined with a predetermined mixture of one or more elements, it is called an aluminium profile alloy. Its end-product performance is determined by both the alloy composition and the method of production. The production method, in turn, strongly influences the final temper of the alloys. Temper is the combination of hardness and strength imparted to a metal by mechanical or thermal treatments. The temper designation is characterized by its metallurgical structures and mechanical properties.

Effects of Alloying Elements
The properties and characteristics of aluminum, such as density, conductivity, corrosion resistance, finish, mechanical properties, and thermal expansion, are modified by the addition of alloying elements. The resulting effect depends upon the principal alloying elements used, as detailed in the table below.
