Notes on Treatment

NICROSIL can be brazed without difficulty. All known welding methods are applicable. However, the alloy is difficult to soft-solder. The thermoelectric voltage of NICROSIL may change as a result of mechanical or thermal stress, see also “Special Remarks on the Alloy”.

Special Remarks on the Alloy

NICROSIL has been developed to eliminate known disadvantages with reference to the positive leg of thermocouple type K (ISATHERM^® PLUS, Chromel^®-P or NiCr10). An increase in the chromium concentration to approx. 14.6 % versus KP will essentially reduce the change in EMF due to the ordering state in the metal lattice.
Thermoelectrically, the alloy therefore is considerably more stable against temperature changes below 600 °C.
NICROSIL reacts corrosively at higher temperatures in the presence of varying oxidizing/ reducing gases. Partial oxidation of the chromium will cause green rot. Sulphur and carbon favor the development of the green rot. As a consequence, the thermoelectric voltage may change dramatically. This oxidation will also lead to brittleness of the material. An increase in silicon concentration will result in higher oxidation stability versus the positive leg of thermocouple type K.

NISIL is used as negative leg of the thermocouple type N. In the version for extension leads NISIL is used for type NN X.
The standardized temperature range of the different application possibilities of NISIL is available in the tables on pages 10 and 11 as well as 14 and 15 in our brochure.

Notes on Treatment

NISIL can be brazed without difficulty. All known welding methods are applicable.
However, the alloy is difficult to soft-solder. See also “Special Remarks on the Alloy”.

Special Remarks on the Alloy

NISIL has been developed as a counterleg to Nicrosil. By increasing the silicon and reducing the aluminium concentration versus the negative leg of thermocouple type K (KN), a higher oxidation stability has been achieved. Consequently, compared to KN the corrosive reaction to sulphur will be lower at higher working temperatures.
