Argentium® International Limited, the owners of the patents to the world-renowned anti-tarnish silver “Argentium® Silver”, has appointed La.Met as it's European manufacturing partner for Argentium® milled products (sheet and wire).

Argentium® Silver is a new kind of silver with outstanding properties:

  • Argentium® Silver is the most tarnish-resistant silver available on the global market, successfully passing four critical tarnish tests to recreate the effects of pollution, perspiration, ultraviolet light and chlorine.
  • Argentium® Silver has a beautiful natural lustre and is a bright white colour which eliminates the requirement for galvanic coating.
  • Argentium® Silver can easily be age-hardened to offer extra strength, durability and scratch-resistance.

La.Met manufactures a vast range of Argentium® Silver milled-products as follows:
