Argentium alloys replace some of the <a href="/facts/Copper/I8PEE8oX">copper</a> in the traditional <a href="/facts/Sterling_silver/fa6mHoon">sterling silver</a> (92.5% <a href="/facts/Silver/xXe41BGg">silver</a> + 7.5% copper) with the <a href="/facts/Metalloid/uMFVXuTq">metalloid</a> <a href="/facts/Germanium/wtoALHGs">germanium</a>. Argentium 935, Argentium 940 and Argentium 960 alloys exceed the standard required for <a href="/facts/Hallmark/j5QnMDVp">hallmarking</a> as <a href="/facts/Sterling_silver/fa6mHoon">sterling silver</a>, and Argentium 960 silver meets the standard for hallmarking as <a href="/facts/Britannia_silver/RhavgHkw">Britannia silver</a> (95.84% silver). </p>
