List of alloys

List of alloys

This is a list of named alloys grouped alphabetically by base metal. Within these headings the alloys are also grouped alphabetically. Some of the main alloying elements are optionally listed after the alloy names.


Alloys of aluminium

Alloys of bismuth

Alloys of cobalt

Alloys of copper

Alloys of gallium

Alloys of gold

The purity of alloys of gold is expressed in karats, which tell you 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 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). 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 and accurately expressed as the result of the ratio, ie: 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.
