Corrosive stability provided by nickel is required not only for large-scale industrial equipment. Many components of electronic devices and equipment for scientific experiments are often subject to hostile environments. As nickel wire and filament is smaller than rods and sheets, they are widely used in electronic and laboratory devices where most components are small. See article "Nickel and fluoride material science" for an example of using nickel products in research and development.
Nickel wire and filament can be purchased on Metotechnics website, via e-mail or by phone.
Technical parameters of semi-finished materials and other useful information are given on this page in the corresponding sections. Product standards also serve as a useful source of information. They can be found on our website.
Марки
Wire is made of NP1, NP2, NP3, NP4 semi-finished nickel, NK0,2 nickel silicide and NMTs2,5 and NMTs5 manganese nickel.
Besides Ni NMTs2,5 grade contains 2.3-3.3 % of Mn, NMTs5 - 4.6-5.4 % of Mn. NK0,2 nickel silicide includes up to 0.25% of Si.
Chemical composition of NP1,..., NP4, NK0,2, NMTs2,5 and NMTs5 grades is regulated by GOST 492-2006.
This NP1, ..., NP4; NK0,2 semifinished product can be supplied both after thermal processing of without it. Round products with diameter 0.09 mm and less are supplied in hard form (hard-drawn); products with diameter higher than 0.09 mm - in hard form (hard-drawn) or soft (annealed) condition. NMTs2,5 and NMTs5 manganese nickel wire with Ø 0.05-0.15 mm is produced in an unnannealed (hard) form; wire with Ø 0.40-5.0 mm - in annealed (soft) or unnannealed (hard) form.
Annealing nickel wire
The size range of the semi-finished products depends on the alloy grade. Thus, NP1,..., NP4 и NK0,2 wire has diameter 0.030 (nickel filament)-12 mm; NMTs2,5 and NMTs5 - diameter 0.050-5.0 mm. Products with small diameter are supplied in spools, products with medium and large diameter - in bundles.
Sizes, supply condition, mechanical properties of the mentioned products are regulated by GOST 2179-75 and GOST 1049-74.
It should be mentioned that nickel wire with small diameter (usually below 0.1 mm) is called “nickel filament”. GOST 25501-82 does not contain definition “filament” for blanks and semi-finished materials, but this term is often used IRL. Also it is often called “micron wire”.

Application
These products are applied in many spheres of science and technology. They are made for using cathodes and grids for electron tubes and microwave device in TV and wireless equipment, electrodes for electrotyping, heating plugs for car, aircraft and tractor engines. Nickel wire serves as a Ni source in vacuum sputtering of coatings made of this metal. Also it is often used in physics and chemistry experiments (e.g., for catalysis grids).
