99% Manganese (Mn) Metal Powder CAS 7439-96-5

Industrial use

The average electric car requires 4.5 kilograms of manganese. Manganese is widely used in automotive batteries, high-end equipment manufacturing, new materials and other fields.

Manganese is used in the production of many important alloys, and in the steel industry, manganese can improve the quality, strength, toughness, stiffness, wear resistance, hardness and hardenability of rollers and castings. Manganese can form high ferromagnetic alloys with aluminum and antimony, especially with small amounts of copper.

Manganese steel is widely used in the manufacture of steel mills, ball bearings, bulldozers and excavators buckets and other frequently worn components, as well as iron manganese manganese rail, bridge and so on. The roof of the audience hall of Shanghai's new Culture Square is made of a novel grid structure welded with thousands of manganese steel pipes. In the fan-shaped hall 76 meters long and 138 meters across, there is not a single pillar in the middle. Because manganese steel is used as a structural material, it is very strong, and the material is less than other steel, and the average roof is only 45 kilograms of manganese steel per square meter.

In the military, high manganese steel is used to manufacture steel helmets, tank steel armor, armor-piercing bullets and so on. When making manganese steel, soft tin ore with manganese content of 60-70% is mixed with iron ore.

Manganese is deoxidized with ferromanganese in steelmaking and remains in steel, manganese has a good deoxidization ability, can reduce FeO in steel to iron, improve the quality of steel; It can also form MnS with sulfur, thus reducing the harmful effects of sulfur. Reduce the brittleness of steel and improve the hot working property of steel; Manganese can be mostly dissolved in ferrite, forming a replacement solid solution, so that the ferrite strengthen and improve the strength and hardness of steel. Manganese is a beneficial element in steel.
