Ferro Alloys
Ferro alloys are alloys of iron together with some element (other than carbon); the most common ores in this entry are ferro-manganese (see separate entry for “ferro manganese”); silica manganese and ferrosilicon (see separate entry on “ferrosilicon”). Ferry alloys are heavy cargoes and normally used as an agent to introduce an element into molten metal, especially into steel or cast iron.

Ferro Silicon Manganese
Silico manganese is an alloy of Iron, Silicon & Manganese. It has higher Silicon content in comparison to Ferro Manganese. Silicon reduces the solubility of carbon in manganese alloys, so carbon contents are inversely proportional to silicon content. It is a more potent deoxidizer of steel compared to Ferro manganese. Deoxidization with SiMn results in cleaner steel than using Ferro Silicon. More than half of the Silico Manganese produced globally is produced in China.
