A light metal is any metal of relatively low density. [1] These may be pure elements, but more commonly are metallic alloys. Lithium and then potassium are the two lightest metallic elements. Magnesium, aluminium and titanium alloys are light metals of significant commercial importance. [2]
Titanium alone is a strong, light metal. It is stronger than common, low-carbon steels, but 45% lighter. It is also twice as strong as weak aluminium alloys but only 60% heavier. Titanium has outstanding corrosion resistance to seawater, and thus is used in propeller shafts, rigging and other parts of boats that are exposed to seawater.
Another metalloid, antimony, features in the strongest known acid, a mixture 10 billion times stronger than carborane acid. This is fluoroantimonic acid H 2 F[SbF 6], a mixture of antimony pentafluoride SbF 5 and hydrofluoric acid HF. [citation needed] Silicon. The thermal conductivity of silicon is better than that of most metals. [citation ...
A durable silvery metal; very light and extremely strong. Mithril means "grey gleam", but is translated as "true silver". [47] It is mined in native form in Moria. It can also be worked into other forms with unusual properties such as reflecting only the light of the Moon. The fictional metal has appeared in other fantasy universes, games, and ...
It is a strong metal with low density that is quite ductile (especially in an oxygen-free environment), [11] ... Titanium's durability, light weight, ...
Van Wert [205] grouped the periodic table metals into a. the light metals; b. the heavy brittle metals of high melting point, c. the heavy ductile metals of high melting point; d. the heavy metals of low melting point (Zn, Cd, Hg; Ga, In, Tl; Ge, Sn; As, Sb, Bi; and Po), and e. the strong, electropositive metals.
Aluminium's ability to form hard yet light alloys with other metals provided the metal many uses at the time. During World War I, major governments demanded large shipments of aluminium for light and strong airframes. While pure metallic titanium (99.9%) was first prepared in 1910 it was not used outside the laboratory until 1932.
Tungsten has the highest melting point among all metals, and its use in light bulbs increases the luminous efficacy and life of incandescent lamps. [ 49 ] The light bulb manufacturer Osram (founded in 1906, when three German companies, Auer-Gesellschaft, AEG and Siemens & Halske, combined their lamp production facilities) derived its name from ...
