Description
45NKH alloy is usedas 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 the alloy 45NKH and the active layer of the alloy 75GND made thermobimetals brand ТБ160/122 (ТБ1613), which is used for the manufacture of temperature-sensitive elements is heated by electric current devices (circuit breaker protection network, relay, etc.).
Note
Thermobimetals ТБ160/122 (ТБ1613) with high coefficient sensitivity (23−28)·10-6 deg-1, with a high specific electric resistance (1,18−1,27) Ohm·mm2/m.
