ferromanganese, all you need to know about it
The composition of ferro manganese can vary depending on the specific type and intended application. However, in general, ferromanganese is an alloy composed primarily of iron (Fe) and manganese (Mn). The manganese content typically ranges from about 65% to 80%, while the iron content can vary within the remaining percentage.
