Differences between Argentium silver and sterling silver What is Argentium silver? Argentium is a new generation silver alloy. It was specifically developed to combat the tarnishing of silver when it oxidizes upon contact with air. However, Argentium silver also has other properties that help make it an extremely versatile alloy for those who choose to work with it. When was Argentium alloy created? Argentium silver was created in 1991 by master silversmith and metallurgist Peter Johns of Middlesex University. It took 10 years of research to produce and was achieved when Metaleurop (which mines and refines metals) contacted Johns regarding two metals they had found; namely indium and germanium, for which they were trying to find new uses. Johns chose to work with germanium and the rest, as the saying goes, is history! What is sterling silver? What is sterling silver made of? Standard sterling silver.
As we know it is made up of 92.5% pure silver with the remaining 7.5% consisting of other metals such as copper, making it harder and more suitable for a wide range of applications. However, that 7.5% copper causes scale (dark stains that occur during prolonged heating) and tarnishes when exposed to air, meaning silver must be cleaned regularly to maintain its appearance. The jewelry industry has tried to overcome this problem with high-quality rhodium-plated silver products, but this BYB Directory obviously comes at an additional cost and is not always feasible for smaller manufacturers (rhodium resists tarnishing and has a beautiful finish. bright white, that's why it is used in white gold and silver, but it is very expensive). So what is the difference between Argentium silver and sterling silver.
As we have mentioned, sterling silver is a popular alloy in jewelry manufacturing, consisting of a mixture of 92.5% pure silver with 7.5% made up of other alloys, usually copper. However, Argentium silver contains a larger amount of pure silver (93.5% pure silver) and the remainder is made up of other alloys, such as a small amount of germanium. This unique addition of germanium gives Argentium silver such beneficial attributes as fire stain resistance, improved durability and also a higher melting point, which translates into a higher annealing temperature and flow point. Additionally, Argentium silver can be cast and soldered much more easily than sterling silver, meaning it is often preferred by goldsmiths. It is also 7 times more tarnish resistant than sterling silver.
