Description
Alloy 50N is used: for the manufacture of cores magdalinova and small power transformers, chokes, relays and parts of magnetic circuits operating at high inductions without bias or with a small magnetization; as the passive layer in the manufacture of thermostatic bimetallic, is used for making sensitive to the temperature change of the elements of control and measuring instruments and apparatus.
When using alloy grade 50N and the active layer of the alloy 24NKH made thermobimetals brand ТБ73/57 (ТБ0831), which is used for the manufacture of thermosensitive elements with a small amount of bending.
Note
Alloy with high magnetic permeability, with the highest value of saturation magnetic flux density of the entire group of iron-Nickel alloys, not less than 1.5 T.
Thermobimetals brand ТБ73/57 (ТБ0831) with low coefficient sensitivity (10−13)·10-6 deg-1, with a low specific electrical resistance (0,55−0,60) Ohm·mm2/m.
