Silver is a relatively soft and extremely ductile and malleable transition metal, though it is slightly less malleable than gold. Silver crystallizes in a face-centered cubic lattice with bulk coordination number 12, where only the single 5s electron is delocalized, similarly to copper and gold. [ 14 ]
Nickel silver, maillechort, German silver, [ 1] argentan, [ 1] new silver, [ 1] nickel brass, [ 2] albata, [ 3] or alpacca[ 4] is a copper alloy with nickel, and often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc. [ 5] Nickel silver does not contain the element silver. It is named for its silvery appearance, which can make ...
"The words "silver" and "sterling silver" describe a product that contains 92.5% pure silver. Silver products sometimes may be marked 925, which means that 925 parts per thousand are pure silver. Some jewelry described as "silver plate" has a layer of silver applied to a base metal. "Coin silver" is used for compounds that contain 90% pure silver.
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...

Silver standards refer to the standards of millesimal fineness for the silver alloy used in the manufacture or crafting of silver objects. This list is organized from highest to lowest millesimal fineness, or purity of the silver. Fine silver has a millesimal fineness of 999. Also called pure silver, or three nines fine, fine silver contains 99 ...
Sterling silver. Sterling silver is an alloy composed by weight of 92.5% silver and 7.5% other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925. Fine silver, which is 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength.
Old Sheffield Plate (or OSP) is the name generally given to the material developed by Thomas Boulsover in the 1740s, a fusion of copper and silver which could be made into a range of items normally made in solid silver. [ 1] The material rapidly gained popularity as a substitute for solid silver, as it was much cheaper to produce.
