About Manganese Alloys
Manganese derives its name from the Latin word Magnes which means Magnet. It is the fourth most used metal in terms of quantity behind Iron, Aluminium and Copper. It was first isolated and recognised as an element in 1774 by a Swedish chemist called Johan Gahn.
Properties Of Manganese
Widespread use of Manganese in steel making began in the UK and France at the beginning of the 19th Century. At the time it was noted that Manganese increased the hardness of Iron without a reduction in its malleability or toughness. In modern steelmaking, Manganese is added in the form of Manganese alloys because of its Sulphur fixing, deoxidising and alloying properties. Nearly all steels contain some Manganese, in proportions that vary from 0.05% to as high as 12%. There are numerous grades of steel each requiring a different amount of Manganese. The average consumption of Manganese is approximately 7-10kgs of Manganese per ton of steel.
Uses Of Manganese
Approximately 90% of all Manganese consumed worldwide goes into the steel industry as an alloying element, and because of its relatively low price and technical benefits it has no real substitute. Manganese also has important uses in Aluminium as an alloying element. It is a versatile addition to Copper alloys and its largest non-metal application is in the form of portable dry batteries. It also has chemical applications and is used as a ceramic and brick colourant.
