This rich, deep yellow master alloy is specially formulated for jewelers working in 18K–22K gold fabrication and investment casting. Designed with granulation techniques in mind, it contains no de-oxidizer, making it particularly well-suited for traditional granulation work. The alloy produces a smooth surface with high luster and performs exceptionally in sheet, wire, and tube making. While optimized for fabrication, it is also suitable for investment casting. Sold per troy ounce (20 pennyweights / 31.1 grams). Contains no gold.
