Crafted from high-quality Super White Alloy #315 (REG), this professional-grade casting alloy is the trusted choice for creating durable, brilliant white gold jewelry in the 10–14K range. Engineered for excellence, this alloy combines superior whiteness, enhanced fluidity, and outstanding mechanical strength, making it ideal for casting intricate pieces with fine detail.

The 10–14K gold compatibility ensures a long-lasting, beautiful finish that closely resembles platinum, but at a fraction of the cost. Whether you’re crafting earrings, necklaces, bracelets, or custom rings, Super White #315 delivers a smooth casting experience and a professional polish. Its versatility makes it a favorite for sample lines, prototypes, and finished production pieces.

This alloy is silicon-deoxidized, reducing porosity and oxidation while improving reusability and temperature control. With a liquidus temperature of 2020°F (1105°C), Super White #315 provides a broad working window that simplifies casting and minimizes common defects like shrinkage or pitting.

Perfect for casting, stamping, wire fabrication, and enameling, this alloy maintains its brilliant white color and requires minimal maintenance. It is also tarnish-resistant and durable enough for everyday wear, making it ideal for high-end or heirloom-quality jewelry.

Thanks to its excellent castability, jewelers can achieve consistent results whether using torch, induction, or resistance melting. Super White #315 is also often used without rhodium plating, thanks to its natural luster and bright finish.
