99.7%/99.9%min Mn Electrolytic Manganese Flakes CAS7439-96-5

Our High Purity Electrolytic Manganese Flakes 99.7%/99.9%min are refer to the elemental metal obtained by acid leaching of manganese ore to obtain manganese salts and then electrolyzing them in an electrolytic cell. It looks like iron, is irregular in shape, hard and brittle, with one side bright and the other rough, ranging from silvery white to brown. When processed into powder, it turns silvery gray. It is prone to oxidation in the air. When encountering dilute acids, it dissolves and displaces hydrogen. At slightly above room temperature, it can decompose water and release hydrogen gas

Application

Electrolytic manganese metal (EMM), typically produced in high-purity flake form, is a critical industrial material with widespread applications due to its excellent metallurgical and chemical properties. Its primary use is as an alloying agent in the steel industry. When added to steel, especially in the production of stainless steel and high-strength low-alloy (HSLA) steels, manganese significantly enhances strength, toughness, hardness, wear resistance, and hardenability. It also acts as a deoxidizer and desulfurizer, improving the quality and workability of the final steel product.

Beyond ferrous metallurgy, electrolytic manganese flakes are indispensable in the manufacturing of non-ferrous alloys. Most notably, they are a fundamental component of aluminum alloys, particularly the 3000 and 5000 series, where they improves corrosion resistance and strength without sacrificing the alloy's formability or lightweight characteristics. This makes such alloys ideal for beverage cans, automotive parts, and construction materials.

Furthermore, electrolytic manganese serves as a crucial precursor in the production of manganese dioxide (EMD) for dry-cell batteries, such as alkaline and zinc-carbon batteries. Its high purity is essential for optimal battery performance. In the chemical industry, it is used to produce various manganese compounds, including manganese sulfate and manganese carbonate, which find roles in fertilizers, animal feed additives, and ceramics. Emerging applications also include its use in advanced lithium-ion battery cathode materials, like lithium manganese oxide, for electric vehicles and energy storage systems.
