NP2: description, application. Nickel wire price
Nickel — metal durable plastic that allows you to make of it a lot of different products. Wire of alloy NP-2 is used the modern industry at least similar products of this brand — sheets, rods, strips, circles. Contains 99.5% nickel, the balance falls on silicon, magnesium, carbon, arsenic, phosphorus, tin, and others.
Until the middle of the eighteenth century, nickel was not known. Extracting copper ore, Saxon miners often greeted this breed, of which could not smelt anything. The miners gave it the name of the harmful gnome Nick bully. Metal could be identified only in 1751 a young Swedish metallurgist Axel Cronstedt, who offered to leave the «popular» nickname of the semimetal. Semimetals called at the time the substance, with the transitional properties between metals and non-metals. Initially attracted only nickel jewelery, and it was impossible to use in the industry. Impurities of sulfur made him fragile. But in the twentieth century with the invention of sulfur removal technology on a commercial scale nickel brilliance eclipsed the luster of gold and silver. A dream come true metallurgists for manufacturing a plurality of stainless steel grades.
Nickel in its pure form is labeled — N, semi-finished — NP depending on the presence of impurities semi-finished nickel wire are digitally coded. NP-2 — the most common series. «H» denotes the title metal itself, and «P» indicates a semi-finished product.

Advantages of NP-2
Pure nickel wire is very hard, sticky and malleable. It is well polished, not in vain the first of its dignity appreciated jewelers. At ordinary temperatures nickel wire coated with a protective film on the air, the oxide, which protects the metal from corrosion. Nickel joined the large number of heat-resistant alloys that resist corrosive liquid and gas at t ° to 850 ° C. Due to the plasticity of nickel available to the most different types of treatment: rolling, drawing, stamping, turning, welding; made very thin nickel wire, a nickel strip, nickel sheet, and so on. n. A disadvantage of the alloy is NP-2 sulfur impurity which is capable of forming on a surface of the film and do sulfide brittle material at high temperatures.
The wire may be rolled from siliceous nickel — used in electronics, and nickel-manganese wire — a mercury-arc rectifiers, spark internal combustion engine. Dragged nickel produced in accordance with GOST 2179−75 in two types: soft wire (which is also called annealed) and solid — cold-worked wire, that is produced by cold pressure to increase strength. Nickel wire must have a clean surface, free from defects or cracks allowed roughness or minor deviations from the declared diameter. Usually, NP-2 wires are made under the order, its diameter can be up to a few microns, for the production of high-tech equipment products must be of such thickness. The quality of such nickel products — the highest. The wishes of the customer are taken into account up to a micron,
Television and radio technology unimaginable without nickel. Wire NP-2 is used for the production of cathodes and grids of tubes and microwave devices. Wire NP-2 can be used as high-impedance nikelevyyprovod resistance thermocouple construction. This wire is indispensable in the manufacture of electrodes electroforming, demand in EDM machines, where the controlled decomposition of electric materials. Wire NP-2 is used for the application of corrosion-resistant nickel deposition. There is a wire starting material for thin nikelevyhpokryty applied to the product under vacuum. The wire is part of the mechanisms operating in a vacuum — its customers are a constant research institutes and laboratories. Industrial chemistry Wire NP-2 is used for catalysis — is the most accessible source of pure nickel. Nickel wire is indispensable for the production of modern electronics, such wire helps to avoid galvanic couples with the same details. Wire NP-2 — is not the only brand also produced nickel wire marks NP-3 and NP-4. This wire has today the most affordable price.
