Description

The Dark Pink-Rose 9–18 All Purpose Master Alloy is a professional-grade casting and fabrication alloy designed for jewelers working across a wide range of gold karatages from 9 to 18 karat. Sold by the troy ounce (20 pennyweight / 31.1 grams), this master alloy contains no gold and is formulated to deliver a warm, dark pink-rose color result when alloyed with gold. Its low silver content and high fluidity make it well suited for investment casting as well as bench fabrication work.
