Description

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.

Features

  • Higher copper, lower silver ratio produces a distinctively darker yellow tone
  • Formulated specifically for investment casting applications
  • Compatible with 10K–14K yellow gold alloying
  • Contains no gold — sold as a master alloy base
  • Sold per troy ounce (20 DWT / 31.1 grams)
  • Proprietary formulation may also include silicon and de-oxidizing elements
