RAFFMETAL SILVAL PRIMARY ALLOYS

PRIMARY ALUMINIUM ALLOYS WITH HIGH RECYCLING RATE AND LOW CARBON FOOTPRINT

Raffmetal, European leader in recycling aluminium scraps for over 40 years, offers SILVAL, an innovative range of primary aluminium foundry alloys from recycling with performances comparable to primary aluminium alloys produced from bauxite. Compared to production from bauxite, the use of recycled aluminium allows lower energy consumption and carbon footprint of our customers’ castings.

Raffmetal know-how allows the application of the most advanced technological solutions in the treatment and selection of scrap, in addition to the strict control of the production process that guarantees a constant high quality.
