The RS4 alloy is a 14kt red gold alloy of the Russia type, developed for investment casting applications and designed to offer high versatility of use.

It is distinguished by its intense and warm red tone, typical of the Russia color, particularly appreciated for its depth and elegance in jewelry creations.

One of the main strengths of the RS4 is the possibility of using it both alone and in addition to silver, allowing the modulation of the color and characteristics of the alloy according to specific production needs. This flexibility makes it suitable for various types of processing and aesthetic results.

From a technical point of view, the alloy guarantees good fluidity during casting, allowing for effective filling of molds and precise reproduction of details, with homogeneous and well-defined surfaces.

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

The RS4 alloy therefore represents a practical and versatile solution for the production of low-karat red gold jewelry and accessories, where flexibility, aesthetic performance, and reliability in investment casting are required.
