Copper-nickel alloys, Dnepropetrovsk region.

"
Copper-nickel alloys are copper alloys, the main alloying element of which is nickel. Nickel forms a continuous series of solid solutions with copper, increases corrosion resistance, hardness, strength, modulus of elasticity and melting point, lowers thermal conductivity, electrical conductivity and temperature coefficient. electrical resistance of the alloy. Copper-nickel alloys are well processed by pressure in hot and cold conditions.(//tractor-service.com)
Sheets, tapes, wire, rods, pipes, etc. are obtained from them. According to their purpose, copper-nickel alloys are divided into structural, spring and electrotechnical ones. The structural alloys include nickel silver and nickel silver, which are used for the manufacture of parts of various appliances, art products, tableware, etc. (lead nickel silver is not subjected to hot processing due to the presence of lead).
