Electrolytic manganese metal flakes (EMM) are used primarily in the production of steel and aluminum alloys, as well as in the manufacturing of batteries, ceramics, and electronic components.

In steel production, EMM is added to the steelmaking process to improve the properties of the steel, such as strength, toughness, and resistance to corrosion. It is also used in the production of some aluminum alloys to improve their mechanical properties and resistance to corrosion.

In the manufacturing of batteries, EMM is used as a cathode material due to its high capacity for storing and releasing electrical energy. It is also used in the production of ceramic materials and electronic components due to its high purity and conductivity.

The advantage of using EMM is that it provides high-quality and consistent performance, which is essential for the production of high-quality steel and other products. Additionally, EMM is relatively low in cost compared to other alloying elements, making it an economical choice for many applications.
