Used to build things,although its use as a structural material is limited since it burns at relatively low temperatures. Extensively in alloys, chiefly with aluminum and zinc, and with manganese.
Magnesium Ingots. Magnesium is the lightest of all the metal elements and is primarily used in structural alloys due to its light weight, strength and resistance to corrosion. Magnesium's characteristics are similar to its sister metal, aluminum. It not only has the lowest density of all the metal elements, making it the lightest, but it is also very strong, highly resistant to corrosion and easily machinable.

Duralumin and magnalium are alloys of magnesium. The metal is also used in pyrotechnics, especially in incendiary bombs, signals, and flares, and as a fuse for thermite. It is used in photographic flashbulbs and is added to some rocket and missile fuels. It is used in the preparation of malleable cast iron. Alone, magnesium metal can be used as a desulpherizer in iron and steel production, as a deoxidizer in the thermal reduction of titanium, zirconium and hafnium, and as a nodularizer in the production of nodular cast iron. Magnesium's characteristics are similar to its sister metal, aluminum. It not only has the lowest density of all the metal elements, making it the lightest, but it is also very strong, highly resistant to corrosion and easily machinable. History: Uses. Magnesium is a commercially important metal with many uses. It is only two thirds as dense as aluminum. It is easily machined, cast, forged, and welded. It is used extensively in alloys, chiefly with aluminum and zinc, and with manganese. Magnesium alloys were used as early as 1910 in Germany. Duralumin and magnalium are alloys of magnesium. The metal is also used in pyrotechnics, especially in incendiary bombs, signals, and flares, and as a fuse for thermite. It is used in photographic flashbulbs and is added to some rocket and missile fuels. It is used in the preparation of malleable cast iron. Magnesium is a chemical substance denoted by the symbol Mg. It forms part of the Group 2 of the periodic table, thus making it an alkaline earth metal. Its atomic number is 12 and it is considered to be the 8th most copious element found in the earth’s crust.  Applications: Because of its similarities with aluminum, magnesium can be used as a substitute for many, if not most, aluminum applications. Magnesium is still, however, limited by its extractions costs, which make the metal about 20% more expensive than aluminum. Magnesium's characteristics are similar to its sister metal, aluminum. It not only has the lowest density of all the metal elements, making it the lightest, but it is also very strong, highly resistant to corrosion and easily machinable. History: Magnesium burns with a brilliant white light and is used in pyrotechnics, flares and photographic flashbulbs. Magnesium is the lightest metal that can be used to build things, although its use as a structural material is limited since it burns at relatively low temperatures. Magnesium is frequently alloyed with aluminum, which makes aluminum easier to roll, extrude and weld. Magnesium is pronounced as mag-NEE-zhi-em. History and Uses: Although it is the eighth most abundant element in the universe and the seventh most abundant element in the earth's crust, magnesium is never found free in nature. Magnesium is an alkaline earth metal that has the symbol Mg in the periodic table of elements. Magnesium is a fairly strong, silvery-white, light-weight metal (one third lighter than aluminum) that slightly tarnishes when exposed to air. Magnesium Strip Electrode. Magnesium Electrode is a strip of magnesium metal about 2 centimeters wide, 12 centimeters long and 1.2 millimeters thick. It is stamped with letters MG so it can easily be distinguished from other metal electrodes with the same size.
