Description

Alloy Lscdm 37,5−10−3,8 used: mainly for the production of ritual goods (wedding rings, crosses); jewelry (rings, earrings, rings, medallions, pendants, brooches, chains).

Note

The gold-silver-copper-palladium alloy. The alloy has poor castability due to the large interval of crystallization, and prone to brittleness when soldering. Products of alloy 375-th sample belong to the cheapest prices and refers to the fading in the air, which limits its use, however, the doping with palladium slightly increases the corrosion resistance.
