Nickel silver is often called Nickel silver or new silver. It is based on copper alloyed with zinc 5−35% Nickel and 13−45%. According to GOST 492−2006 alloy can contain cobalt, iron or other additives. Dependent on the percentage composition of Nickel silver may acquire a bluish or greenish sheen.
The basic qualities
This is a relatively mild alloy density 7.5 g/cm3, melts at t° to 1024 °C. the hardness of the 80 kg/mm, Nickel greatly improves corrosion properties of the alloy, and the copper gives it ductility and toughness. Nickel silver is characterized by elasticity, strength, resistance to moisture condensation, it is easily polished. Good plasticity allows it to deform both hot and cold.
Regulates the production of long products and flat products series 12−24 mnts, mnts 15−20, 18−20 mnts, mnts 18−27 — state standard 492−2006. The Nickel-silver mnts 15−20 doped Ni at 13.5−16.5%, Zn 18−22%, is a solid solution, or single-phase alloy of these metals. This alloy is perfectly stamped. The dishes and Cutlery of this alloy is always covered with silver or gold, to eliminate metallic taste. The coating thickness of the silver is Cutlery — 24,00±3,60 m; for knife handles — 18,00±of 2.70 microns. The gold is applied to the sublayer of the silver — 0,500±0,075 µm. Manufacture of Cutlery Nickel silver normalizes GOST 24320−80.
Manufacturing electrical equipment, precision instruments, silver plated ware, the so-called Nickel silver, jewelry, medical instrument and equipment, working in contact with water or steam.
From China to Europe in the 18−19 centuries, was imported honey products under the name «Patpong» Nickel silver, usually silver plated. Also called German silver, Chinese silver. Nickel silver brand ISC 15−20, used for exclusive jewelry, superior in toughness and wear resistance alloy silver 925°, containing 92.5% of Ag doped is 7.4% Cu.
