How Silver-Filled Metals Are Made

Silver-filled, like gold-filled, consists of precious metal (silver) bonded to a base metal substrate (a red brass alloy, CDA #220). The 1/20 and 1/10 notation refers to the ratio of silver to brass core by weight, which is 5% and 10%, respectively. All of Rio’s silver-filled products are made with quality sterling silver.

Silver-filled jewelry is highly economical; your customers enjoy the bright white look of silver at a fraction of the cost.

The value of silver-filled is greater than silver-plated because silver-filled has an actual layer of sterling silver, not just a microscopic film.

In 1/10 silver-filled, 10% of the total weight of the metal is silver.

In 1/20 silver-filled, 5% of the total weight of the metal is silver.

In single-clad sheet, the silver layer is bonded to one side of the sheet of brass.

In double-clad sheet, discs and other findings, silver layers are bonded to both sides of the sheet of brass.

The weight of the silver will be either 10% or 5% of the total weight of the sheet in either case. On the single-clad sheet, all of the silver is bonded to one side; on the double-clad sheet, the silver is distributed so that half is bonded to one side and half to the other side.
