1. The Essential Sterling Silver Alloying Agent

Copper is the traditional and vital component for turning fine silver into durable, beautiful Sterling Silver (0.925).

When alloying, our pure copper shot ensures your finished product meets the industry standard of 92.5% silver and 7.5% copper. Using 99.9% pure copper eliminates guesswork and provides the strength, resilience, and characteristic warmth needed to prevent your fine silver pieces from becoming too soft for daily wear. Use it confidently to achieve perfect hardness and a rich, subtle patina over time.

2. Stunning Pure Copper Casting & Fabrication

Beyond alloying, pure copper offers a unique aesthetic for standalone pieces. Casting or fabricating with 99.9% copper allows you to capture its distinctive, warm reddish-gold hue and its natural ability to take on incredible detail.

Perfect for:

• Casting: Pour detailed, solid pieces that celebrate copper’s unique color and density.

• Forging: Utilize copper’s high ductility for shaping and forming unique jewelry components.

• Mixed Media: Incorporate it alongside other metals for contrasting color combinations.

Whether you're crafting heirloom sterling pieces or pioneering pure copper designs, our 99.9% Pure Copper Shot is the foundation for your next masterpiece.
