The term “Electrum” denotes the native gold–silver alloy that provided humanity with some of its first experiences with metallurgy.

Traducción de 'copper and silver alloy' en el diccionario gratuito de inglés- español y muchas otras traducciones en español. Electrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals. It has also been produced artificially, and is often known as green gold . [ citation needed ] The ancient Greeks called it 'gold' or 'white gold', as opposed to 'refined gold'. Gold and silver unite in all proportions, yielding alloys which are harder, more fusible, and more elastic than either metal. The hardest is that containing two parts of gold to one of silver. The colour of gold is sensibly lowered by the addition of very small quantities of silver, and on increasing the proportion About Silver Gold Alloy Silver Gold is one of numerous metal alloys sold by American Elements under the trade name AE Alloys™ . Generally immediately available in most volumes, AE Alloys™ are available as bar, ingot, ribbon, wire, shot, sheet, and foil. The silver-gold alloys most used in jewellery are green gold (silver 25, gold 75), dead-leaf gold (silver 30, gold 70), and the alloy containing 40 per cent, of silver. Triple alloys of gold, silver, and copper are employed far more frequently by English jewellers than those last mentioned; of these the alloys, consisting of 22-, 18-, 15-, 12-, and 9-carat gold respectively, can be hallmarked, Alloys of gold and silver were much used for coinage before the methods of parting became well

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 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, Gold is a soft metal and is usually alloyed to give it more strength. It is a good conductor of heat and electricity, and is unaffected by air and most reagents. It is one of the least reactive chemical elements. Gold is often found as a free element and with silver as a gold silver alloy. Dealloying of the gold and silver alloy is usually accomplished in one of two ways: acid etching or electrochemical etching. Acid corrosion is a chemically straightforward process that is used for selective removal of silver. Silver alloys are commonly used in the creation of jewelry. Sterling silver (92.5 percent silver and 7.5 percent copper) and Britannia silver (95.84 percent silver and 4.16 percent copper) are cheaper than gold or platinum. They are also used to make tableware and are used as currency in many nations.

Gold and copper are the only two metals that exhibit colour. Owing to this property, gold alloys can be made to assume a range of colours by varying the alloying additions. In 862 BC the Lydians were using coins made of a green gold-silver alloy known as ‘electrum’ and composed of 73wt%Au and 27wt%Ag.

The term “Electrum” denotes the native gold–silver alloy that provided humanity with some of its first experiences with metallurgy. Pure gold, 24kt, is very soft and not suitable for jewelry making. The alloy metals used with gold give it strength so it can be made into beautiful lasting jewelry. Beyond the strengthening purpose, alloying allows for colored gold. The most common colors of gold today are white gold and rose gold. Alloys used in jewelry making range from 9-karat gold, approximately 37% pure gold, to 24-karat gold. They are required to be stamped and hallmarked according to purity . A newer alloy becoming popular on the jewelry scene consists of 99% gold and 1% titanium. Gold and copper are the only two metals that exhibit colour. Owing to this property, gold alloys can be made to assume a range of colours by varying the alloying additions.
