Silver (Ag).

It was called white silver (white metal). And it is often used as an adornment from its white glow. Among precious metals, output is relatively large and it is inexpensive.
Pure silver is very soft and vulnerable. And it is used in the form of alloy with other metals since it has oxidation and darkening properties. Plating such as rhodium is often applied to make it difficult for darkening.
The silver grade division is also expressed in thousands. Especially Silver 900 (Ag 900) is called coin silver, Silver 925 (Ag 925) is called Sterling Silver.
Nickel silver, Mailechort, German silver, Argentan, new silver, nickel brass, albata, alpacca, or electrum is an alloy composed of copper, zinc and nickel, not silver.


白銀(白い金属)と呼ばれていたことがあり、その白い輝きから装飾品として利用されることが多い。貴金属のなかでは比較的産出量も多く安価である。
純銀はとても柔らかく傷つきやすい。また、酸化して黒ずみやすい性質があるため、他の金属との合金の形で利用される。また、黒ずみにくいようにロジウムなどのメッキが施されることも多い。
銀の品位区分もまた千分率で表され、なかでもとくに、Silver900(Ag900)はコインシルバー、Silver925(Ag925)はスターリングシルバーと呼ばれている。
洋白は、銅、亜鉛、ニッケルからなる合金で、銀ではない。
