The 45 alloy for 18-22 kt gold is a characteristic yellow-green alloy, designed to offer versatility and quality in both plastic working processes and investment casting without stones.

Thanks to its formulation, it ensures excellent workability in sheeting, rolling, and stamping operations, maintaining a good balance between ductility and strength. In the investment casting phase, it presents good fluidity and allows for precise castings, with uniform and well-defined surfaces.

Its particular yellow-green tone makes it particularly interesting from an aesthetic point of view, especially in productions that involve the combination with red gold and white gold. In these cases, the 45 alloy allows for creating harmonious and elegant contrasts, enhancing the design of the product.

The homogeneous structure and stability of the material facilitate subsequent processing and finishing, making it an ideal choice for high-quality jewelry and accessories, where aesthetic rendering, chromatic compatibility, and production reliability are required.
