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.
A refractory metal is a metal that is very resistant to heat and wear. Which metals belong to this category varies; the most common definition includes niobium, molybdenum, tantalum, tungsten, and rhenium as well as their alloys. They all have melting points above 2000 °C, and a high hardness at room temperature. Several compounds such as ...
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Light Metal Age is a technical trade magazine exclusively devoted to primary production, secondary production, and semi-fabrication of light metals, specifically aluminum, titanium, magnesium, beryllium, and their alloys.
David points out that dark metal conducts heat even better than light metal, so if you're looking for extra speed and browning, seek out dark metal pans. "Think of wearing a white t-shirt versus a ...
From December 2008 to December 2012, if you bought shares in companies when Edward A. Kangas joined the board, and sold them when he left, you would have a 71.0 percent return on your investment, compared to a 60.5 percent return from the S&P 500.
Fire-retardant materials are designed to burn slowly.. Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat.
