Abstract: Aluminum and aluminum alloy usage has a great economic and social importance. Therefore, so customary in our lives, aluminum and its alloys have a great spread in various fields. Our paper presents possibilities for optimization of aluminum (Al) alloys elaboration and casting processes by specific mathematical modeling. Some of these developments might include: developing new furnace types that will replace the largely exposed melt surface with a reduced surface area, thus improving energy consumption, environmental performance and overall efficiency through reduced metal loss; the development of in–line metal treatment units through high speed degassing. Direct and reliable detection and measurement techniques of non-metallic measurements will be developed; continuous production processes will replace sequential operations used to produce tin foil, extruded products and remelted alloyed ingots. We also present the main modeling principle and we describe the algorithm of modeling. Recycling provides a viable solution to existing shortages of raw materials. The use of products made with secondary aluminum provides high energy savings compared to the same products that use primary aluminum. Recycling aluminum products has a positive impact on the environment, its recyclability being preferred over other materials. An important principle of mathematical modeling is the principle of analogy. This principle consists in observing and analyzing competently the modeled reality, using both analogy with other fields of research and logical homology.
