Silval Special Alloys Plant has been an active manufacturing facility since 2020.
As of 2025, it is fully owned by Raffmetal, the leading European producer of aluminum alloys from recycling.
Thanks to its expertise in scrap processing and sorting systems, along with state-of-the-art facilities, it stands out as a unique producer of primary aluminum alloys from recycling, capable of offering high-quality products with a low Carbon Footprint.
Silval Special Alloys Plant produces exclusively for Raffmetal, European leader in the recycled aluminum sector for over 40 years, and offers the market an innovative range of primary aluminum alloys from recycling with performance comparable to primary aluminum alloys produced from bauxite. The use of recycled aluminum, compared to production from ore, allows for a reduction in energy consumption and the Carbon Footprint of final products, including castings, rolled products and extrusions.
Technological know-how in scrap treatment and selection, along with strict process control, ensures high and consistent quality.
