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]
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
Al-Li alloy powder is used in the production of lightweight sporting goods, including bicycles, tennis rackets, golf clubs, and baseball bats. Its high strength combined with reduced weight significantly enhances performance, speed, and maneuverability.
This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically. Within these headings, the alloys are also grouped alphabetically.
This page lists metals, with subdivisions for alloys and specialised subsets of metal and metal-based compounds. ... Light metal; M. Metal foam; Metal hydroxide ...
The most common lightweight metals are aluminium [12] [13] and magnesium [14] [15] alloys. Schematic appearance of round metal bars after tensile testing. (a) Brittle fracture (b) Ductile fracture (c) Completely ductile fracture. Metals are typically malleable and ductile, deforming under stress without cleaving. [10]
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.
Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required. [1] Alloys composed mostly of aluminium have been very important in aerospace manufacturing since the introduction of metal-skinned aircraft. Aluminium–magnesium alloys are both lighter than other aluminium alloys ...
