Professional laboratory and scientific and technological research in the field of electronics, electrical engineering and other areas related to or used in their work (production) processes:
- Physical features of electric low-frequency pulses with minimum values of voltage and current.
- Chemical processes static magnetic fields arising from the interaction of certain active substances.
- Compact current transformers low frequency.
- Chokes and relays to secure the presence of even the weakest magnetic fields.
- Nickel Ni – 79-80% the basis for obtaining high-quality composition.
- Iron Fe, from of 13.73 to 16.8% is the main binder.
- Manganese Mn – 0,6-1,1%.
- Titanium Ti – 0.15%.
- Aluminium Al – 0.15%.
- Molybdenum Mo – 3,8-4,1%.
Completed rather complicated equipment and precision instruments for carrying out measurements of electric and magnetic characteristics. They have to create or keep track of the slightest changes and deviations using:
Which must be equipped with cores with the so-called highest category of electromagnetic permeability, for the manufacture of which used the alloy 79NM. He qualifies in the technical handbooks as precision alloy soft magnetic type.
Classification according to GOST
Used for manufacturing major parts for precision equipment and instrumentation, alloy 79NM corresponds to a rather strict, established by GOST 10994-74 year parameters in its qualitative composition of the components. As a percentage it looks like this:
Copper Cu – not more than 0.2%.
the Main indicator for quality – Brinell hardness number (120-210 MPa) electrical resistivity (2×10-5 Ohms). At the metallurgical enterprises of the alloy produced in the cold rolled format, with a classification of – tape 79 nm corresponding to parameters of GOST 10160-75 year.
Get more information on the magnetically soft alloy 79NM you can use the official website of the company engaged in the supply of various sizes of rolled it (strip, rod, sheet, forging) in the domestic market directly from manufacturers. Presented in the resource directory of products fully meet the quality parameters on the structure and format of production.
