It is a new material made using the same manufacturing method as gold filled, which is popular as an accessory material. It is mainly made of an alloy such as brass (yellow brass) as the core, and is coated with a 5% silver alloy, which accounts for 1/20 of the total weight. The quality of the silver alloy used in silver filled is sterling silver. Sterling silver is a silver alloy cast with a silver content of 92.5% or more and less than 7.5% of other metals. Alloying metal is a metal used in alloys for the purpose of increasing strength and durability, and in sterling silver, copper is mainly used as an alloying metal at a ratio of less than 7.5%. Due to this copper in the alloying metal, sterling silver has a unique, calm luster and color that is different from pure silver. The hardness of the wire varies depending on the inner material. The hardness of half-hard wire also varies depending on the manufacturer.
