Silver-filled is a new layered metal that was introduced during the recent surge of silver prices during the recession. Δεν είναι κράμα επειδή η περιεκτικότητα σε μέταλλο δεν είναι η ίδια σε όλο το υλικό. Αντί, the sterling silver is all on the surface. Ασημένιο γεμάτο είναι είτε 5% ή 10% sterling silver by weight fused with heat and pressure to a brass core. This metal is fairly new so it is not standardized in the US. Δεδομένου ότι το ασήμι είναι ένα μέταλλο με στρώματα, δεν μπορεί να χυθεί. The silver layer is much thicker than silver plate but this is still a much lower quality product than solid sterling silver jewelry supplies and alloys. It will tarnish and it should only be soldered with precision equipment and special training. Now that the price of silver has come down from past highs the metal is less common in the market. There is no legally approved quality stamp standard for silver-filled at this time. Ωστόσο, some use the stamp .925 SF, which can be misleading.
