The 48 alloy is a gold alloy of 18-22 kt color, designed to provide excellent aesthetic performance and reliable performance in both plastic working and investment casting without stones.

Characterized by a high silver content and a low zinc percentage, this alloy offers a bright, clear, and shiny yellow tone, with a uniform and refined appearance. The high silver content contributes to improved color brightness, while the reduced zinc content favors greater chromatic and qualitative stability.

From a technical standpoint, the 48 alloy ensures good ductility, making it suitable for processing such as rolling, drawing, and stamping, with stable behavior during deformation. In investment casting, it offers good fluidity and effective mold filling, allowing the production of well-defined parts with high-quality surfaces.

Its homogeneous structure and ease of processing in subsequent stages, such as polishing and finishing, make it ideal for jewelry and accessories applications where elegance, surface quality, and production reliability are required.
