Scrap-Intensive Wrought Aluminum Alloys of Standard Quality
Abstract
To remain competitive, wrought aluminum alloys should offer the customer improved mechanical properties, achieved through recycling. To ensure this, it is necessary to organize a scrap yard with different material streams, each with a proper and well-controlled chemical composition, and to develop the software for calculating the proper combination of material streams that is essential for achieving the required alloy composition. An algorithm was developed for calculating the optimum combination of material streams for providing the standard composition of the pre-melting mixture, the required mechanical properties of the alloy and the minimum cost of production within the entire processing chain. It does not favour in advance the formulation of alloys with an increased amount of scrap, but selects a solution based on the optimum cost of production. The algorithm is also useful for tailoring recycling-friendly compositions of wrought aluminum alloys and for optimizing the production technology.
