The SUPER4 alloy is a red gold "Russia" 14 kt alloy developed to offer high performance in both investment casting and plastic working, distinguishing itself by the absence of silver in its composition.

This characteristic allows for achieving a particularly intense, warm, and stable red Russia tone, ideal for jewelry applications where a strong chromatic identity is required.

From a technical standpoint, the alloy guarantees a good balance between ductility and resistance, making it suitable for processes such as rolling, drawing, and stamping, with reliable behavior during deformation. In investment casting, it offers good fluidity and effective mold filling, allowing for the production of pieces with homogeneous surfaces and well-defined details.

The compact structure and metallurgical stability facilitate subsequent processing, such as polishing and finishing, further enhancing the depth and brilliance of the red color.

The SUPER4 alloy therefore represents a versatile and high-performance solution for the production of low-karat red gold jewelry and accessories, where chromatic intensity, reliability, and quality in production processes are required.
