Magnesium is a silvery-white metal which possesses the lowest density among the industrial metals. Because of low mechanical properties industrial magnesium is not applied as structural material. Properties of magnesium can be significantly improved by adding of alloying elements. Magnesium alloys are characterized by low density, high specific strength and good ability to absorb vibrations. The main alloying hardeners in magnesium alloys are aluminium and zinc. Magnesium alloys are used in manufacture of forged and stamped intricate parts, such as aircraft impellers and cowl gils and automobile disks. Due to low density and high specific strength magnesium alloys are widely used in aircraft building. Theu are appied in manufacture of housing units, pumps, lamps and cabin doors. In rocketry magnesium alloys are used to manufacture rocket airframes, fairings, stabilizers, fuel tanks. In short-duration missiles, such as air-to-air missiles and guided missiles, magnesium alloys constitute the great bulk of a structure. Casting alloys are used in manufacture of brackets, rakers, ailerons, tail fin parts, and wrought alloys are used in hull platings, stringers, longerons and other parts. Nuclear power engineering is also an important magnesium application field. Due to the ability to absorb thermal neutrons and the non-availability of interaction with uranium and good thermal conductivity, magnesium alloys are used in the manufacture of fuel claddings in nuclear reactors.
