Complex of research and development work aimed at implementation of jewellery palladium based alloys technology has been carried out at JSC Krastsvetmet. A range of palladium alloys jewellery fabrication has been organized. Compositions of a number of jewellery palladium alloys grade 850, 900, 950 and 990 have been proposed, their production and application in jewellery manufacture has been organized. To produce palladium alloys induction melting in inert atmosphere and melt pouring into a copper mould has been used. The ingots heat treatment conditions, as well as semi-finished jewelry plastic deformation parameters have been determined.
