Alloying with these elements increases strength characteristics, increases ductility, lowers melting temperatures, and increases the plasticity of the base material. Gold-silver alloy has a higher strength Qualitative characteristics of the alloysĮlectrum is an alloy that may contain other metals in addition to silver: copper, palladium, platinum. The modern Russian classification classifies it as a green precious metal. In Greek it is called λευκὸς χρυσός (leukos chrysos). This led to the description of the alloy with silver as white gold.

The earliest coins were found on the territory of the ancient kingdom of Lydia, Eastern Greece. This is due to the high wear resistance, increased hardness. It was mined in ancient Greece and was widely used to make coins. It was imported from mines located on the African continent.
