AlphaSil410This alloy is suitable for 925-950 carat sheets, continuos castings, stone in and without stone castings. It contains some grain refiners, hardeners and specific deoxidizers which highly protects the alloy from tarnishing . This is the reason that AlphaSil410 has the highest resistance to tarnishing and oxidizing amongs the other silver alloys. There is no need to rhodium plating because of its high shineness and long term stability for tarnishing conditions.
