Gold is the best known among the precious metals used for jewerly production. Its unique characteristics of color, ductility and rarity make it the most desirable of metals, and the one where most committment by Legor Group Research and Development is concentrated.
Gold jewelry production poses today a large amount of challenges, starting from compliance with international standards, to jewels weight reduction, to the need for improved workability or better scraps re-usability, to high tarnish resistance in lower titles, to name but a few.
Legor Group master alloys for gold are available in all the titles and all the production processes applicable on the Market. They represent a range of products unrivalled for variety, reliability and advantages offered.
Silver is, from the point of view of quantity worked, the most common metal in the jewelry sector. It is well known to have processing issues such as tarnishing, unsatisfactory hardness, porosity, firestain.
Legor Group, in a constant research to avoid any processing limitation, proposes specific product lines:
The production of platinum at title 950 and 900 has always been a challenge in the creation of optimal quality objects. Legor Group research has therefore concentrated on improving the process characteristics most important for revolutionising the common platinum alloys at title 950 and 900.
The result is PlatOne, a line of products of superior class in terms of fluidity, hardness and resistance to wear, in which the positive characteristics of each of the base products have been maintained.
Advantages of the PlatOne line:
• Superior resistance to abrasion
• Less susceptibility to scratching and wear
• High resistance against bending
• Superior surface quality
• Ease of processing in both the casting and finishing phase
Palladium is a platinoid element with a characteristic white shade and that can be used not only in nickel-free white gold alloys, but also for the production of palladium based alloys at title 950 and lower.
Our palladium based alloys are an interesting, cost-effective alternative to the most commonly used platinum and white gold jewelry alloy; they are the result of a research and development work focused on improving the alloys' fluidity, reusability and as cast hardness.
Our copper-based alloys in drops designed for costume jewelry and fashion items are the perfect choice for those who manufacture non-precious jewelry and fashion accessories. We offer an extremely wide range of solutions, all characterized by the following winning points.
HIGH PURITY: Our products are made starting from high-end quality, oxygen-free raw materials and produced in strictly controlled processes. Designed without lead, cadmium or any other noxious elements as alloy components.
REGULATIONS COMPLIANCE: Tolerances on impurities in our products are much stricter than what currently requested by international regulations on chemical substances.
PRODUCT CERTIFICATION: Every batch of our products is supplied with technical specifications and certifications of conformity.
PERFORMANCE AND STABILITY: These formulations are conceived to operate smoothly in production, obtaining reduction of defects, and the guarantee of a reliable production process.
High-end purity raw materials and pre-alloys, for internal production of alloys.
A wide variety of semi-finished items (wire, sheet, foil, tube) of different materials (copper, iron, tombac, brass) that can be used as cores to help the goldsmith in complex mechanical working processes such as the production of hollow jewelry, or as materials for the production of non-precious jewelry.
