Manganese and Zinc – About Elements

Manganese

Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.

Zinc

In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.

Manganese and Zinc – Applications

Manganese

Manganese is an important alloying agent. Almost 90% of the manganese produced annually is used in the production of steel. In steels, manganese improves the rolling and forging qualities, as well as strength, toughness, stiffness, wear resistance, hardness and hardenability. The second largest application for manganese is in aluminium alloys. Aluminium with roughly 1.5% manganese has increased resistance to corrosion through grains that absorb impurities which would lead to galvanic corrosion. Manganese can be formed into many useful compounds. For example, manganese oxide, which can be used in fertilizers and ceramics.

Zinc

Corrosion-resistant zinc plating of iron (hot-dip galvanizing) is the major application for zinc. Coating of steel constitutes the largest single use of zinc, but it is used in large tonnages in zinc alloy castings, as zinc dust and oxide, and in wrought zinc products. Galvanized steel is just plain carbon steel that has been coated with a thin zinc layer. The zinc protects iron by corroding first, but zinc corrodes at much lower rates than do steel. Other applications are in electrical batteries, small non-structural castings, and alloys such as brass. A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate (as dietary supplements), zinc chloride (in deodorants), zinc pyrithione (anti-dandruff shampoos), zinc sulfide (in luminescent paints), and dimethylzinc or diethylzinc in the organic laboratory. A key part of the modern materials world in which zinc finds itself is recycling. Zinc, in common with all metals (and unlike synthetic materials) can be recycled indefinitely without degradation.
