Silver-filled is a new layered metal, introduced during the surge of silver prices during the recession. Det är inte en legering eftersom metallinnehållet inte är detsamma i hela materialet. Silverfylld är antingen 5% eller 10% sterling silver by weight, fused with heat and pressure to a brass core. Eftersom silverfylld är en skiktad metall kan den inte gjutas. The silver layer thicker than silver plated, but this is still a much lower quality product than most solid silver alloys. Now that the price of silver has gone down, this metal is less common in the market. There is no legally approved quality stamp standard for silver-filled pieces at this time.
