Gold is the most desirable of metals

It is also the best known among precious metals, thanks to its unique characteristics of colour, ductility and rarity.
Manufacturing a gold jewel poses today a large amount of challenges, from compliance with international standards, to weight reduction, to the need for improved workability or better scraps re-usability, to high tarnish resistance in lower titles.
Legor master alloys for gold are available for all the titles and all the production processes applicable on the market.
They are a range of products unrivalled for variety, reliability and advantages offered.
