The company Avecglobal sells at a reasonable price from the manufacturer a bulk metal — wire, a circle and a rod, which is made of copper-nickel alloy Neusilber brand CuNi18Zn20 (also called CW 409). The supplier guarantees the timely delivery of products to any address. specified by the consumer.

Composition and application

The alloy Neusilber CuNi18Zn20 (CW 409) belongs to the group of copper-nickel alloys, which are additionally doped with zinc. The alloy is characterized by good plasticity, high corrosion resistance, as well as tarnish resistance (the latter, in conjunction with a pleasant silvery eye, often causes the use of this material in jewelry).

Typical applications of CuNi18Zn20 (CW 409): in consumer equipment and items — components of various musical instruments, optical instruments, radiotelephones, nameplates, suit fittings, camera parts, sports weapons, cutlery, zippers.

In addition, the alloy Neusilber CuNi18Zn20 (CW 409) is used for the production of fastening products: screws and rivets. In industry and construction, the alloy in question is used for making decorative patterns, bases, supports and other decorative items.

The alloy chemical composition, which meets the technical requirements of the UNS C76400 standard, is presented below:

Cu: 60.0… 63.00%
Ni: 17.00… 19.00%
Fe: not more than 0.25%
Pb: not more than 0.05%

Mn: not more than 0.50%

Zn: the rest.

Note. The copper used for the production of the alloy Neusilber CuNi18Zn20 (CW 409) must have a chemical purity of at least 99.5%.
