Aluminum Alloys France | A-S 12 UGN

A-S 12 UGN is a cast aluminum-silicon alloy with a high silicon content (around 12%), known for its excellent wear resistance, low thermal expansion, and good mechanical strength, even at elevated temperatures. It is particularly suited for forged or machined components in the automotive, aerospace, and high-performance engineering sectors, such as pistons, engine blocks, and structural elements under thermal and mechanical stress. While its corrosion resistance is moderate, it offers excellent dimensional stability and machinability. At Rosswag, we use advanced open-die forging and precision machining to produce high-quality components from A-S 12 UGN. Its thermal stability and wear resistance make it ideal for demanding applications in dynamic and high-temperature environments.
