Innovation Challenge: Argentium Silver - Middlesex University

22 Sep 2014

Argentium is a sterling silver alloy with unique properties and has inspired jewellers to develop designs retailing in over 1220 British High Street shops.

Middlesex's research showed that Germanium possessed many properties in alloy with silver - fire scale elimination; high tarnis resistance; precipitation hardening and simple heat-hardening properties; increased ductility; increased thermal and electrical resistance (making alloys suitable for welding and laser forming); and environmental advantages (associated with not having to remove, or plate over, fire scale).

This research has contributed to the total tonnage of the new alloy shipped which is quite difficult to estimate but around 40 tonnes of Argentium are currently being sold annually making a significant contribution to the specialist market for unique silver alloy.
