List of named alloys#Silver

{{Short description|None}}

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. Some of the main alloying elements are optionally listed after the alloy names.

Alloys by base metal

=Aluminum=

{{main|Aluminium alloy}}

  • AA-8000: used for electrical building wire in the U.S. per the National Electrical Code, replacing AA-1350.Hunter, Christel (2006). [http://www.aluminum.org/AM/CM/ContentDisplay.cfm?ContentFileID=59083 Aluminum Building Wire Installation and Terminations] {{Webarchive|url=https://web.archive.org/web/20140205073955/http://www.aluminum.org/AM/CM/ContentDisplay.cfm?ContentFileID=59083 |date=2014-02-05 }}, IAEI News, January–February 2006. Richardson, TX: International Association of Electrical Inspectors.
  • Al–Li (2.45% lithium): aerospace applications, including the Space Shuttle
  • Alnico (nickel, cobalt): used for permanent magnets
  • Aluminium–Scandium (scandium)
  • Birmabright (magnesium, manganese): used in car bodies, mainly used by Land Rover cars.
  • Devarda's alloy (45% Al, 50% Cu, 5% Zn): chemical reducing agent.
  • Duralumin (copper)
  • Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons
  • Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion
  • Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira
  • Magnalium (5-50% magnesium): used in airplane bodies, ladders, pyrotechnics, etc.
  • Ni-Ti-Al (nickel 50%, titanium 40%, aluminium 10%), also called Nitinol
  • Y alloy (4% copper, nickel, magnesium)

Aluminium also forms complex metallic alloys, like β–Al–Mg, ξ'–Al–Pd–Mn, and T–Al3Mn.

  • Megallium (cobalt, chromium, molybdenum)
  • Stellite (chromium, tungsten, carbon)
  • Talonite (tungsten, molybdenum, carbon)

The purity of gold alloys is expressed in karats, (UK: carats) which indicates the ratio of the minimum amount of gold (by mass) over 24 parts total. 24 karat gold is fine gold (24/24 parts), and the engineering standard{{citation needed|date=February 2016}} is that it be applied to alloys that have been refined to 99.9% or better purity ("3 nines fine"). There are, however, places in the world that allow the claim of 24kt. to alloys with as little as 99.0% gold ("2 nines fine" or "point nine-nine fine).{{citation needed|date=February 2016|reason=needs a citation, also needs to remove implied POV pejorative}} An alloy which is 14 parts gold to 10 parts alloy is 14 karat gold, 18 parts gold to 6 parts alloy is 18 karat, etc. This is becoming more commonly{{citation needed|date=February 2016}} and more precisely expressed as a decimal fraction, i.e.: 14/24 equals .585 (rounded off), and 18/24 is .750 ("seven-fifty fine").

There are hundreds of possible alloys and mixtures possible, but in general the addition of silver will color gold green, and the addition of copper will color it red. A mix of around 50/50 copper and silver gives the range of yellow gold alloys the public is accustomed to seeing in the marketplace.{{citation needed|date=January 2019|reason=needs a citation to prove the stated facts re numbers and colours}}
