The 425M alloy is a 14Kt yellow gold Hamilton alloy specifically developed for investment casting applications, offering a balanced combination of aesthetic appeal and technical performance.

It is distinguished by its warm, slightly intense yellow Hamilton tone, particularly prized for its elegance and ability to confer a rich and distinctive appearance to finished products.

From a technical standpoint, the alloy ensures good fluidity during casting, allowing for effective mold filling and precise reproduction of details, even in complex geometries. Surfaces are homogeneous and well-defined even in the rough state.

The compact structure and metallurgical stability contribute to reducing defects and porosity, facilitating subsequent processing such as polishing and finishing, and further enhancing the brightness of the color.

The 425M alloy therefore represents an ideal solution for the production of low-karat gold jewelry and accessories, where aesthetic quality, reliability in investment casting, and distinctive color are required.
