Refined Ferrosilicon 72 For Foundries
Low-impurity refining grade
Stable inoculation performance
Cost-efficient foundry additive
Product Overview and Performance Characteristics of FeSi 72 for Foundry Use
Refined Ferrosilicon 72 for Foundries is produced with a stable silicon content of 72 percent and controlled impurity levels to support cast iron inoculation, melt conditioning and general alloy adjustment. This grade provides a balanced combination of performance and cost efficiency, making it a preferred choice for medium-scale foundry operations.
The refined composition ensures clean melt reactions and reduces the risk of unwanted inclusions, supporting stable graphite formation and improved mechanical properties of cast products. FeSi 72 dissolves uniformly in molten iron, delivering predictable silicon recovery and supporting consistent inoculation results. With reliable supply capacity and steady industrial behavior, it is suitable for foundries requiring dependable metallurgical inputs without excessive material cost.
