Sandvik Kanthal Thermothal N Thermocouple wire
Categories:	Metal; Nonferrous Metal; Nickel Alloy
Material Notes:	Thermothal N is an austenitic nickel alloy (Ni alloy) used for the negative leg of thermocouples type K. Thermocouples type K have a good resistance to oxidation and better than other combinations of thermocouples. Thermothal N can not be exposed to atmospheres containing sulphur gases Information provided by Sandvik
