Description

Alloy SRM 83 is used: for the manufacture of tableware (spoons, forks, knives, coasters, dishes, blades, shovels, cups, glasses, sugar bowls, tea strainer); ritual and ceremonial items (wedding rings, crosses); jewellery for personal adornment (rings, rings, medallions, pendants, brooches, chains, bracelets, pins, cufflinks); cigarette cases and cigarette holders; commemorative medals and badges.

Note

Alloy silver-copper. With the increase of copper content in the alloy increases its hardness, but alloy becomes yellowish. The oxygen in the alloy increases the hardness and fragility.
