Natural silver is mostly alloyed with gold, mercury, antimony, copper or platinum, and natural gold is almost always alloyed with small amounts of silver. China's ancient known amber gold, known in English as ELECTRUM, is a natural alloy of gold and silver, containing about 20% silver.
Silver (Argentum), a transition metal. Chemical symbol Ag. Silver is one of the metals known and utilized in ancient times, and is an important precious metal. Silver in nature, there are monomers, but the vast majority of them are in the form of chemical compounds present in the silver ore. The physical and chemical properties of silver are more stable, thermal and electrical conductivity is very good, soft, rich ductility. Its reflectivity is extremely high, up to 99% or more. There are many important uses.

Pure Silver Applications:
Pure silver is very malleable, and has the highest electrical and thermal conductivity of any metal. Silver is commonly used to make extremely sensitive physical instrument components, various automated devices, rockets, submarines, computers, nuclear devices, and communication systems, all of which have a large number of contact points made of silver. During use, each contact has to work millions of times and must be wear-resistant and reliable to withstand the rigors of the job, and silver is perfectly suited to meet these requirements. If rare earth elements are added to silver, the performance will be even better. With this kind of silver with rare earth elements produced by the contact point, life can be extended several times.
