Description

A general-purpose master alloy for alloying with pure silver to produce .925 sterling silver. Sterling-Classic White Alloy delivers a classic white color and is well suited for both casting and fabrication applications. Sold per troy ounce (20 pennyweights / 31.1 grams).

This alloy is formulated with less zinc and more copper compared to the Super White 846-597N alloy, making it a distinct choice for jewelers who prefer that specific balance of workability and finish.

Contains no silver. The alloy is heat treatable, exhibits high fluidity during casting, and offers good tarnish resistance.
