The consumption of medium and low carbon ferromanganese in cast irons manufacturing in the US is forecasted to decrease over the coming years. In 2023, consumption stood at 382 metric tons. By 2024, it is expected to be 380.87 metric tons, decreasing to 374.57 metric tons by 2028. This represents a year-on-year decline of 0.43% to 0.42% from 2024 to 2025 and continues at a similar rate through 2028. The five-year compound annual growth rate (CAGR) averages at a decline of 0.43% annually.

Future trends to watch for include:

Developments in alternative materials that could impact demand for ferromanganese.
Technological advancements in cast iron manufacturing that may reduce material usage.
Regulatory changes related to environmental policies affecting production methods.
