GENERAL INFORMATION

Alloy Nimo®79  – is a magneto-soft iron-nickel alloy with the content of nickel around 80% and 4,2-5,2% of molybdenum, saturation magnetic induction is about 0,8 T. Alloy has the highest technically received magnetic permeability, and very low coercitivity.

Typical application of alloy Nimo®79:

- toroidal spiral cores for the built-in current transformers

- measuring transformers, inductive components;

- plates, cores of transformers; induction components;

- shielding – for protection against magnetic influence in the form of a magnetic film;

- details of step engines;

- relay details;

- other products with a low coercive force.

MAGNETIC PROPERTIES

At toroidal spiral cores initial magnetical inductive capacity µ4, can reach from 160000 to 380000, and maximal magnetical inductive capacity from 320000 to 480000 at frequency 50Hz and strip thickness 0,065 mm. The static coercitivity, as a rule is 1 A/m. The hysteresis loop, can be curved, rectangular or straight. The magnetic properties stated above are reached by means of special annealing. Annealing is made at temperature 1050-1200^оС lasting from 2 up to 8 hours. Especially important in case of alloy Nimo®79 to cool at a temperature 300-600^оС, as it considerably influences magnetic properties.

CORROSION RESISTANCE

Resistance to corrosion has an average value in the damp atmosphere.
