The new alloys developed by Legor at T.Gold 2021

The new alloys developed by Legor at T.Gold 2021

NI1811: Legor's low nickel release line

Nickel is the cheapest and most performing whitening agent for obtaining white gold. According to the European regulation, however, the use of nickel in jewelry production must be controlled and regulated through a release test. Legor has developed NI1811: the line of 750 ‰ (18 Kt) white gold low nickel release alloys. This line has proven to be as performing as our traditional alloys with a higher nickel content. Another advantage of the NI1811 line is the less amount of rhodium present in the composition. This is the result of a research carried out by R&D laboratory aimed at verifying what is the minimum rhodium title necessary to give stability in the result, in order to provide customers with the best performing alloys at the lowest price.

PTLUX: the alternative to rhodium

Nowadays the price of rhodium is constantly rising. Companies in the jewelry and fashion accessories sector find themselves having to make a choice: increase prices, change materials, or find new solutions. Legor Group and its cutting-edge R&D laboratory are always looking for new ways to meet market demands. To cope with the drastic increase in the price of rhodium, the company presents an alternative: PTLUX, a new galvanic process that allows the electrodeposition of platinum in an alloy with a minor percentage of ruthenium. PTLUX has been created with the aim of obtaining a precious finish, even whiter than pure platinum, at a lower price than rhodium and less subject to market fluctuations.
What are the characteristics of this alloy?
• Whiter color than pure platinum (reduction of the b-coordinate *)
• Additional savings compared to pure platinum deposition
• Easy to use
• Good performance as an intermediate layer before final finishing

Legor precious metals are 100% recycled

CoC stands for Chain of Custody. Thanks to this certification, Legor is able to guarantee the integrity and document every single step from source to retail of the entire production chain. Each link in this chain is critical to ensure that the metals are tracked and come only from certified sources. The CoC standard, in fact, defines the requirements for the creation of the chain of custody of precious metals from the mine to the final consumer, ensuring that the various stages from processing to marketing take place in a responsible manner. To date, out of more than 1,000 companies that are part of the RJC, only just over a hundred are CoC certified. In addition to the CoC certification, Legor took a further step, choosing to introduce only precious metals from recycled sources into production. Precious metals used in Legor HQ are therefore 100% recycled.
