Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

High-carbon ferromanganese is a carbon-saturated ferroalloy that contains up to 7.5 percent carbon.1

In addition to this carbon content, the alloy typically consists of 76 to 80 percent manganese, 12 to 15 percent iron, and up to 1.2 percent silicon. This material is produced through smelting processes in either a blast furnace or an electric furnace, where manganese oxides are reduced by carbon.12
