Standard Yellow 9-14 Investment Casting Master Alloy-Per Troy Ounce (20DWT)

A reliable, professional-grade investment casting master alloy formulated to produce a darker yellow tone ideal for 10K–14K gold alloying. This alloy contains no gold and is sold per troy ounce (20 pennyweights / 31.1 grams), making it a cost-effective base for custom casting work. With a higher copper content and reduced silver compared to similar casting alloys, it delivers a warmer, deeper yellow color well-suited to yellow gold casting applications.
