FeSi 75 Lump Grade For Alloying
50–100 mm lump format
Stable alloying performance
Low-impurity refining grade
FeSi 75 Alloying Grade: Composition Profile and Functional Behavior
FeSi 75 Lump Grade for Alloying is manufactured with a silicon content of 75 percent and controlled impurity levels to support stable alloying behavior in refining and casting processes. The 50–100 mm lump size provides efficient furnace charging and predictable dissolution, allowing operators to achieve consistent silicon delivery with minimal process deviation.
This grade is designed to meet alloying requirements where clean melt reactions, low aluminum levels and reliable silicon recovery are critical. Its strong mechanical strength reduces breakage during handling and supports stable furnace performance. FeSi 75 Lump is widely used in steelmaking and alloy-steel production scenarios where purity, stability and efficiency are essential.
