Argentium Silver

So what is Argentium, and why was it created? Argentium is one of a new generation of silver alloys. It was developed specifically to combat the tarnish that occurs as silver oxidises when it comes into contact with air, which is a major drawback for all who love silver. But that?s not the only reason. Argentium also boasts a whole range of other properties besides this, which help to make it an exceedingly clever alloy for those who choose to embrace it.

The main difference between Argentium silver and sterling silver is their composition. Sterling silver is 92.5% pure silver and other metals – usually copper. Argentium silver has higher purity levels – either 93.5% or 96% pure silver – with germanium added. This germanium gives Argentium silver fire stain resistance, improved durability, a higher melting point, and makes it easier to fuse and weld. Additionally, Argentium silver is seven times more tarnish-resistant than sterling silver.

Sterling silver is an alloy made up of 92.5% pure silver and 7.5% other metals, usually copper. This combination enhances the metal's hardness and durability, making it suitable for a variety of applications, especially in jewellery. However, the copper content can cause tarnishing and fire scale (dark staining during heating), which means sterling silver items require regular cleaning to maintain their appearance.

One of the main selling points of Argenitum silver vs. sterling silver is its resistance to tarnishing. But does Argentium silver tarnish at all? While it is tarnish-resistant, it?s worth making sure that tools you use on the Argentium silver do not have excess residue from other metals on them, as this could cause cross-contamination and leave your work slightly tarnished. If possible, keep your polishing buffs for use with Argentium separate from those that used with other alloys. In very simple terms, if you replace the copper in silver with germanium, you increase the tarnish resistance significantly. However, this subtle difference between Argentium and sterling silver also results in a metal that is stronger, whiter, and easier to fuse and weld. Argentium silver also comes with lower temperature hardening capabilities ? which is great news for the silversmith!
