The L05 alloy is a red gold alloy 8–14 kt designed to offer versatility and reliable performance in both plastic working and investment casting without stones.

It stands out for the absence of silver in its composition, a characteristic that contributes to a more pronounced and stable red tone, particularly suitable for specific aesthetic applications.

From a technical point of view, the alloy ensures a good balance between ductility and resistance, making it suitable for processes such as rolling, drawing, and stamping, with stable behavior during deformations. In investment casting, it offers good fluidity and mold filling capacity, allowing the production of pieces with homogeneous surfaces and well-defined details.

Thanks to its color and composition, the L05 is particularly indicated for the production of bi- and tricolor objects, where it allows for clear and elegant chromatic contrasts with white and yellow gold.

The L05 alloy therefore represents an ideal solution for low-karat jewelry and accessories, where chromatic definition, production versatility, and aesthetic quality are required.
