Description

Alloy Clsrm 37,5−25 is used: for the production of jewelry (rings, earrings, rings, medallions, pendants, brooches, chains).

Note

The gold-silver-copper alloy. The alloy is suitable for all kinds of cold processing and molding. Products of alloy 375-th sample belong to the cheapest prices and refers to the fading in the air, which limits its use.
