Elemental magnesium is a gray-white lightweight metal, two-thirds the density of aluminium. Magnesium has the lowest melting (923 K (1,202 F)) and the lowest boiling point 1,363 K (1,994 F) of all the alkaline earth metals.
Pure magnesium is brittle and easily fractures along shear bands. It becomes much more ductile when alloyed with small amount of other metals, such as 1% aluminium.[14] Ductility of polycrystalline magnesium can also be significantly improved by reducing its grain size to ca. 1 micron or less.[15]
Magnesium is a silver-white metallic element and the lightest of all structural metals. Magnesium is available in two principal forms, pure and alloy. Pure magnesium in unwrought form contains at least 99.8 percent magnesium by weight.26 Alloy magnesium is an alloy
Magnesium Ingots can be used in the production of magnesium alloy, as well as for use in chemical industrial, military industrial and meter instrument manufacture, etc.
Magnesium is used in super-strong, lightweight materials and alloys. For example, when infused with silicon carbide nanoparticles, it has extremely high specific strength. Magnesium, being readily available and relatively nontoxic, has a variety of uses:
As a reducing agent to separate uranium and other metals from their salts.
As a sacrificial (galvanic) anode to protect boats, underground tanks, pipelines, buried structures, and water heaters.
Alloyed with zinc to produce the zinc sheet used in photoengraving plates in the printing industry, dry-cell battery walls, and roofing.[35]
As a metal, this element's principal use is as an alloying additive to aluminium with these aluminium-magnesium alloys being used mainly for beverage cans, sports equipment such as golf clubs, fishing reels, and archery bows and arrows.
