The 400M alloy is a green gold alloy developed specifically for investment casting applications, designed to ensure casting quality and a distinctive aesthetic finish.

It is characterized by a well-defined and recognizable green tone, ideal for creations that require chromatic originality and a strong visual impact.

From a technical standpoint, the alloy offers good fluidity during casting, allowing for uniform filling of molds and precise reproduction of details, with homogeneous and well-defined surfaces even in the rough state.

The 400M alloy is particularly suitable for the production of bi- and tricolor objects, where its green color allows for the creation of elegant and dynamic contrasts in combination with yellow and red gold, enhancing the design of the piece.

The compact structure and metallurgical stability facilitate subsequent processing, such as polishing and finishing, further improving the surface quality and final appearance.

The 400M alloy therefore represents an ideal solution for multicolored gold jewelry and accessories, where precision in investment casting, aesthetic finish, and design versatility are required.
