Legor Group has always been renowned in the world for its core business product: master alloys.
The continuous innovation, the real and valid operational support to customers and the high productive standards qualify the Master Alloy Division of Legor Group as the reference trade name in the international gold and silver market.
In the production of jewellery the use of gold and silver as pure metals does not allow to obtain products that stand up under wear and tear, or which have a high level of mechanical resistance, or important performance in terms of colour and malleability. Master alloys are the answer to specific and increasingly complex productive requirements. The term master alloy is understood as a particular category of non-ferrous alloy (metallic materials made up of several metals), primarily of copper, silver, nickel and zinc. Thanks to the use of the right master alloy, containing grain refiners and deoxidizers, it is possible to influence the characteristics of a jewel, such as colour, hardness, mechanical resistance, malleability and resistance to oxidation. The variety of these parameters justifies the large number of characterising compositions in Legor Group production; in fact, it is preferable to have various compositions for various types of processing or carat weight. This allows to obtain an obvious advantage from the operational point of view and to optimise the final product.
Legor Group Master Alloy Division offers a qualified service of subcontract analyses and technical consultancy, using the internal Research and Development laboratory, highly sophisticated and equipped with advanced instruments for any kind of metallurgical analysis (from quality control to development of new products and process solutions).
