The 445M alloy is an 8-14 kt gold alloy characterized by a yellow tone with green undertones, designed as an economical solution for investment casting applications.

It is distinguished by a particular and recognizable color, suitable for productions where an original chromatic effect is desired while maintaining good cost control.

From a technical standpoint, the alloy offers good fluidity during casting, allowing for effective mold filling and satisfactory detail reproduction, with relatively homogeneous surfaces even in the rough state.

The metallurgical structure ensures reliable workability and facilitates subsequent finishing operations, such as polishing and surface treatments, improving the final appearance of the product.

The 445M alloy therefore represents a practical and efficient choice for the production of low-karat gold jewelry and accessories, where economy, distinctive aesthetic performance, and good investment casting performance are required.
