The 400 alloy is an 8-14 kt gold alloy characterized by a particularly distinctive and vibrant green color, ideal for applications requiring a strong chromatic impact.

Thanks to its unique tone, it is particularly suitable for creating bi- and tricolor jewelry, where it allows for the creation of elegant and original contrasts in combination with yellow, red, or white gold, enhancing the design of the piece.

From a technical standpoint, the alloy is designed to provide good performance in both plastic working operations, such as rolling, drawing, and stamping, and investment casting without stones. It offers a good balance between ductility and strength, allowing for stable and reliable processing.

In investment casting, it presents good fluidity and mold-filling capacity, enabling the production of pieces with homogeneous surfaces and well-defined details.

The 400 alloy therefore represents an ideal solution for the production of low-karat gold jewelry and accessories, where chromatic originality, production versatility, and aesthetic quality are required.
