NiCr-NiAl (Type K)  thermocouple wire
NiCr NiSi (Type K) thermocouple wire finds the widest use in all base metal thermocouple, at temperature above 500°C.The main chemical composition of  positive leg NiCr (KP) are Ni≈90% and Cr≈10%; negative leg NiAl (KN) are Ni≈97% and Al≈3%. The operating temperature range is -200~1300°C(for short term) and 0~1100°C( for long term).
Type K thermocouple wire has strong resistance to oxidation than other base metal thermocouple bare wire . It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:
(1) Alternatively oxidizing and reducing atmosphere,
(2) Atmosphere with sulphur gases 
(3) Long time in vacuum
(4) Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere.
