Specific weight of manganese, properties, uses and value table

Manganese is a chemical element and transition metal widely used in metallurgy. In nature it occurs in ores and minerals, and in industry it is especially important as an additive to steels and alloys.

Manganese is present in many types of cast iron and steel. It is used for deoxidation, sulfur binding, and improving the strength, wear resistance and impact toughness of metallic materials.

Table of manganese specific weight

The specific weight of manganese depends on its crystalline modification, purity and temperature. For reference calculations, an average value of about 7.3-7.4 g/cm³ is often used. A noticeable spread in values can be related to impurities and the condition of the sample.

The table below gives approximate density and weight values for 1 m³ for the main modifications of manganese.

Properties of manganese

Manganese has a silvery-gray color with a slight reddish tint. In pure form it is fairly hard but brittle. Without significant iron content, manganese usually does not show pronounced magnetic properties.

The melting point of manganese is about 1246 °C, and its boiling point is about 2061 °C. When exposed to oxygen, the metal surface becomes covered with a thin oxide film.

The main industrial value of manganese is related to its ability to improve steel properties. In alloys, it increases strength, hardness, resistance to impact loads and wear. Manganese is also part of some non-ferrous alloys, such as manganins, which are used because of their stable electrical resistance.

Manganese is required by living organisms in small amounts as a trace element, but excessive amounts of its compounds can be toxic. Therefore, safety requirements must be followed when working with manganese dust and compounds.

Applications of manganese

Manganese is widely used in metallurgy as a deoxidizer and alloying additive. Adding significant amounts of manganese to steel makes it possible to obtain wear-resistant and impact-resistant materials, such as high-manganese steels for crushing, earthmoving and railway equipment.

Manganese is also used in the production of ferromanganese, silicomanganese, bronzes, brasses, chemical reagents, battery materials and special alloys with specified electrical properties.
