Manganese metal flakes
Manganese is a chemical element, designated by the symbol Mn. It has the atomic number 25. We are the most prominent suppliers of all grades and forms of Manganese Metal. It is found as a free element in nature (often in combination with iron), and in many minerals. Manganese is a metal with important industrial metal alloy uses.
High Speed Steel Rolls
Manganese Metal
Manganese is often found in nature, combined with iron and many other minerals. It is a pinkish-gray, chemically active element with important industrial metal alloy uses.
The metal is hard to melt but gets easily oxidized. Manganese is highly reactive when pure, as powder, it will burn in the presence of oxygen, and rust in water containing dissolved oxygen.
Applications
Manganese is essential for iron and steel production as it is a key component of low-cost stainless steel formulations and certain widely used aluminum alloys. Manganese dioxide is used as a catalyst to decolorize and make violet-colored glass.
Potassium permanganate is a potent oxidizer, commonly used as a disinfectant. Manganese oxide (MnO) and manganese carbonate (MnCO3) are other compounds with practical uses. MnO is used in fertilizers and ceramics, while MnCO3 is the starting material for making other manganese compounds.
In Copper Alloys:
Manganese is probably the most versatile element to be added to copper alloys. A small amount of manganese (0.1% – 0.3%) is added to deoxidize the alloy and improve its castability and mechanical strength. Manganese has a high solid solubility in copper and binary systems with copper and aluminum, zinc, or nickel as the binary constituent. Many commercial copper alloys include around 1 to 2% manganese to improve durability and workability. Manganese can be used to replace nickel in nickel-silver alloys to reduce costs.
In Aluminum Industry:
Manganese is used as an alloying element up to its solubility limit of about 1.5%. Aluminum-manganese alloys and aluminum-manganese-magnesium alloys, usually marketed under different trade names, are generally used in different fields such as kitchenware, roofing, car radiators, and transportation. To date, aluminum-manganese alloys are mostly used for manufacturing beverage cans, which sell more than 100 billion units yearly. The market for aluminum-manganese cans has grown steadily due to its recyclability.
Aluminum alloys containing up to 9% Mn have promising properties, but cannot be economically produced yet as the processes used are expensive and can only be applied to high-value materials used in the aerospace industry.

Other Applications: Manganese is used in zinc alloys, but only 0.1 to 0.2% of its content is added. It can also be used in magnesium alloys with the same content range, except for an alloy with 1.5% Mn.
Manganese can also be added to gold, silver, and bismuth to create alloys specifically designed for applications in the electronic industry.
