18K NICKEL & PALLADIUM FREE ALLOYS
BLANK® is a family of ready-to-use 750‰ white gold alloys developed to meet the demand for Nickel & Palladium free solutions. Already pre-alloyed with gold and ready for direct use, BLANK® offers a practical and industrial alternative to traditional white gold alloys, ensuring reliable production behaviour and good whiteness. Designed for both casting and deformation processes, BLANK® supports manufacturers looking for a versatile, compliant and cost-conscious solution.
Designed for Reliable Nickel & Palladium Free White Gold Manufacturing
BLANK® is engineered to provide a Nickel & Palladium free alternative while maintaining the key properties required for jewellery production. Supplied as a ready-to-use 750‰ alloy, it simplifies alloy preparation and supports greater consistency during production. Its formulation ensures stable metallurgical behaviour across both casting and mechanical processes, making it suitable for industrial manufacturing environments. The alloy offers good workability and sufficient plasticity for standard operations such as forming and stone setting. Compared to traditional white gold alloys, BLANK® combines regulatory compliance with a more efficient cost structure. The absence of palladium contributes to reducing alloy cost, while the lower density of the alloy allows manufacturers to produce the same jewellery volume with less material weight, reducing precious metal consumption.

Frequently Asked Questions
BLANK® is a ready-to-use 750‰ white gold alloy that is completely Nickel & Palladium free, offering a compliant alternative to conventional white gold alloys while maintaining suitable mechanical and processing properties for jewellery manufacturing.
BLANK® reduces production costs through two main factors: the absence of palladium and its lower density. Traditional palladium-based 18K white gold alloys can reach densities of approximately 15.8 g/cm³, while typical nickel-based white gold alloys are around 14.7 g/cm³. BLANK® has a density of approximately 14.4 g/cm³, making it lighter than both. This means that for the same jewellery design and volume, less alloy is required. For example, a jewel weighing 10 g when produced with a palladium-based white gold alloy would weigh approximately 9.1 g when produced with BLANK®, resulting in a saving of approximately 0.9 g of alloy. Since 18K alloys contain 75% gold, this corresponds to a reduction of approximately 0.7 g of fine gold per piece. Compared to traditional nickel-based white gold alloys, the weight reduction is smaller but still measurable. In medium and high production volumes, these differences can generate significant savings while maintaining the same visible volume and design.
Yes, BLANK® can be used in both investment casting and plastic deformation processes. Its versatility makes it suitable for a wide range of jewellery applications depending on specific production requirements.
