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.
Specific weight and weight of 1 m3 of manganese
| Material | Specific weight (g/cm3) | Weight of 1 m3 (kg) |
|---|---|---|
| Alpha manganese | 7.44 | 7440 |
| Beta manganese | 7.29 | 7290 |
| Gamma manganese | 7.21 | 7210 |
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.
Frequently Asked Questions
Can the density of manganese be used for precise calculations?
The density and weight values for manganese in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of manganese differ from the table?
The actual weight of manganese depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of manganese from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of manganese is given in kg/m³ and the volume is in m³, the result will be in kilograms.
