Argentium silver 935 is a modern sterling silver alloy, containing 93.5% silver. The traditional sterling alloy (92.5% silver + 7.5% copper) is modified by removing some of the copper and adding the metalloid germanium. Argentium silver 960 is a higher-purity jewellery alloy also containing germanium.
What Is Coin Silver? As its name suggests, coin silver is the type of material that makes up silver dollars and other pieces of silver currency. It’s a standardized alloy that’s comprised of a very limited number of non-silver metals like copper and nickel. In the United States, coin silver must be at least .900 fine.
Silver is a naturally occurring free element and pewter is an alloy. The main element in pewter’s composition is tin; more than 90% of its composition is tin and copper, antimony, bismuth and lead are the rest. Silver is used as an alloy and as a pure metal. Both silver and pewter had been used for thousands of years by the human. Silver is considered as a precious metal since its abundance on the earth is low.
