Manganese serves as an important alloying agent. Many different types of manganese alloys are available in the market today, including ferro manganese alloys, copper manganese alloys, high manganese alloys, and nickel manganese alloys, to name a few. Manganese is possibly the most flexible element that can be added to copper alloys.

Updated on March 10, 2020. The 200 series is a class of austenitic and highly corrosion-resistant stainless steels that are characterized by having low nickel content. They're also referred to as chrome-manganese (CrMn) stainless steel . Austenitic steels include both the 200 and 300 series. They're defined by their face-centered cubic structure.

The SLC30A10 protein may also transport manganese out of brain cells to protect them from an accumulation of the element. Mutations in the SLC39A14 gene impair the transport of manganese into liver cells, allowing the element to build up in the blood. When levels are high in the blood, manganese accumulates in brain cells.
