Ferro Silicon Aluminium is a multi-element alloy with a silver-gray metallic appearance at room temperature. It typically contains 5–40% silicon, 15–55% aluminum, and the balance iron.
FeSiAl is a highly efficient deoxidizer widely used in steelmaking. It improves inclusion morphology, reduces gas content in molten steel, and enhances overall steel quality—while also lowering production costs and saving aluminum.
Production methods include direct furnace loading with blended raw materials or pre-treatment before charging, depending on process requirements.
