ALUMINIUM INGOT

The treatment of aluminum scrap to produce new aluminum metal and alloys is an alternative to primary Al production. The chemical composition of the alloys is strictly related to the scrap quality. Therefore, recycled aluminum presents a certain amount of impurities, generally not present in primary alloys, and the alloying elements are more difficult to manage.

Nowadays, this distinction is not completely exhausting. By properly selecting high quality scrap, a purity level close to primary alloys can be achieved in secondary alloys too.

Iron (Fe) plays an important role in distinguishing between primary and secondary Al alloys. This element cannot be easily removed from the molten metal and it forms generally brittle intermetallic compounds that influence the final mechanical properties of the components.

Primary Al alloys present low Fe content and so they are used for applications where the best exploitation of some specific properties is required (mechanical strength, ductility, corrosion resistance, workability, weldability, electrical conductivity); secondary alloys show good castability, which, combined with the natural low volume density of Al alloys, makes them suitable in high-pressure die casting.

It is intended to prepare a Feasibility Report to install 7200Tons/Year Aluminium Ingot production facility as a Green Field Project.
