electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. the term is also used for electrical oxidation of anions on to a solid substrate, as in the formation of silver chloride on silver wire to make silver/silver-chloride electrodes.
continuous casting, also called strand casting, is the process whereby molten metal is solidified into a 'semifinished' billet, bloom, or slab for subsequent rolling in the finishing mills. prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. since then, 'continuous casting' has .
a fusible alloy is a metal alloy capable of being easily fused, i.e. easily meltable, at relatively low temperatures. fusible alloys are commonly, but not necessarily, eutectic alloys. sometimes the term 'fusible alloy' is used to describe alloys with a melting point below 183 c 361 f; 456 k . fusible alloys in this sense are used for solder .
the coinage metals comprise, at a minimum, those metallic chemical elements which have historically been used as components in alloys used to mint coins. the term is not perfectly defined, however, since a number of metals have been used to make 'demonstration coins' which have never been used to make monetized coins for any nation-state, but could be.
specific alloys are used in oil and gas downhole applications and nickel hydrometallurgy for their high strength e. g.: titanium beta c alloy , corrosion resistance, or both. the pulp and paper industry uses titanium in process equipment exposed to corrosive media, such as sodium hypochlorite or wet chlorine gas in the bleachery .

for low temperature melting point alloys, such as zinc or tin, melting furnaces may reach around 500 c 932 f . electricity, propane, or natural gas are usually used to achieve these temperatures. for high melting point alloys such as steel or nickel-based alloys, the furnace must be designed for temperatures over 1,600 c 2,910 f .
an alloy of 96% zinc and 4% aluminium is used to make stamping dies for low production run applications for which ferrous metal dies would be too expensive. for building facades, roofing, and other applications for sheet metal formed by deep ding, roll forming, or bending, zinc alloys with titanium and copper are used.
the ames project also studied thorium, alloying it with bismuth, carbon, chromium, iron, manganese, molybdenum, nickel, oxygen, tin, tungsten and uranium, and alloyed beryllium with bismuth, lead, thorium, uranium and zinc. chemistry. the chemistry of uranium was the focus of multiple studies by the ames project.
copper–zinc brass alloys are currently 2011 being deployed in commercial-scale aquaculture operations in asia, south america and the us hawaii . extensive research, including demonstrations and trials, are currently being implemented on two other copper alloys: copper-nickel and copper-silicon.

in 1738 nehemiah's son william champion patented a technique for the first industrial scale distillation of metallic zinc known as distillation per descencum or 'the english process'. this local zinc was used in speltering and allowed greater control over the zinc content of brass and the production of high-zinc copper alloys which would have .
in printing and typography, hot metal typesetting is a technology for typesetting text in letterpress printing. this method injects molten type metal into a mold that has the shape of one or more glyphs. the resulting sorts or slugs are later used to press ink onto paper. normally the typecasting machine would be controlled by a keyboard or by a paper tape. hot metal typesetting was developed in the late nineteenth century as a development of conventional cast metal type. the technology had seve
indium is a minor component in zinc sulfide ores and is produced as a byproduct of zinc refinement. it is most notably used in the semiconductor industry, in low-melting-point metal alloys such as solders, in soft-metal high-vacuum seals, and in the production of transparent conductive coatings of indium tin oxide ito on glass.
