Nickel 200 is the most widely used standard grades of commercially available pure brought Nickel along with and Nickel 201. These alloys offer good thermal conductivity, mechanical properties, resistance against many corrosive environments, in particular against caustic alkalis, low electrical resistivity, and good magnetostrictive properties.
Nickel 200 is easily workable by forming and drawing. Nickel 201 is a low carbon variation of Ni200 and has a very low work hardening rate which allows it to be easily cold formed. It also offers better creep resistance and is preferred over Ni200 for applications that experience temperatures over 600°F (315°C).

Fe-CuNi thermocouple (type J) is also named Fe- Constantan thermocouple. The positive leg Fe(JP) is made by pure Iron, and the main chemical composition of negative leg Constantan (JN) is Cu: Ni≈ 55%: 45%. Although they are all called Constantan, JN does not give the same EMF output curve as EN and TN, it cannot be instead by other Constantan.

Cu-CuNi thermocouple (type T) is also named Cu- Constantan thermocouple. The positive leg Cu(TP) is made by pure Copper, and the main chemical composition of negative leg Constantan (TN) is Cu: Ni≈ 55%: 45%. Although EN, TN, JN are all called Constantan, TN and EN don not give the same EMF output curve as JN. EN and TN are able to interchange but they are not interchangeable with JN. The operating temperature range of type T thermocouple is -200~350℃, Due to the low resistance of oxidation that Copper has, it is not advisable to go beyond that range.

Nicrsi-NisiMg (Type N) thermocouple is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. The main chemical composition of positive leg Nicrsi (NP) is Ni: Cr: Si≈84.4: 14.2: 1.4; negative leg NisiMg (NN) is Ni: Si: Mg≈95.5: 4.4: 0.1. Type N thermocouple also be used in the similar atmospheres that type K works, and the operating temperature range is -200~1300℃.

NiCr-NiSi (Type K) thermocouple finds the widest use in all base metal thermocouple, at temperature above 500℃。The main chemical composition of  positive leg NiCr (KP) are Ni≈90% and Cr≈10%; negative leg NiSi (KN) are Ni≈97% and Cr≈3%. The operating temperature range is -200~1300℃(for short term) and 0~1100℃( for long term)
