Nickel chrome wire is a kind of non-magnetic alloy of nickel and chromium, it is widely used in heating elements. The maximum operation temperature of the heating elements is related to the wire diameter, it is better to choose thicker wires, the corrosive atmospheres also have a considerable relationship with the maximum operation temperature. The surface temperature is about 100C higher than the inner normally, when the operation temperature exceeds the limit, the oxidation of heating elements itself is accelerated, the heat resistance will be reduced, which is easily deformed,collapsed and even appreas to be broken, thereby shortening the service life.
Pure nickel wire has good mechanical strength, corrosion resistance and high heat resistance. It is suitable for making electrical vacuum devices, electronic instrument components, and corrosion resistant materials.
Copper nickel wire has good mechanical strength, corrosion resistance and low resistance. It is suitable to make thermal components in low-voltage electrical appliances such as thermal overload relays, low-voltage circuit breakers and household appliances. Copper nickel alloys are also the key materials for manufacturing geothermal cables.
Type J thermocouple alloys is suitable for using in vacuum, oxidizing and reducing atmospheres or inert gas atmospheres. Because of high temperature oxidizing quickly for JP, the measuring temperature range is restricted. The composition of positive(JP) is Fe100, negative(JN) is Cu55Ni45.
Type K is the most common thermocouple conductor(≥500℃), it has a good resistance against oxidation and can be recommended for oxidizing and inert atmospheres.It can not be used in sulphurous and vacuum atmospheres directly at a high temperature,as this will have a significant impact on the EMF values. The composition of positive(KP) is Ni90Cr10, negative(KN) is Ni97Si3.
Type T thermocouple conductor is suitable for temperature below 0℃ with an upper temperature limit of 350℃(ASTM E230:370℃) and can be used in oxidizing and reducing atmospheres or inert gas atmospheres,The composition of positive(TP) is Cu100,negative(TN) is Cu55Ni45.
Type E bare thermocouple wire develops the highest source voltage(EMF) per℃ for measuring tiny temperature shift,it is suitable in oxidizing or inert gas atmospheres up to 900℃(ASTM E230:870℃), The composition of positive(EP) is Ni90Cr10, negative(EN) is Cu55Ni45.
Type N thermocouple conductor is suitable in the similar atmospheres with type K and the operating temperature is -200-1300℃. Its advantage is thermoelectric stability. The composition of positive(NP) is approximately Ni84.4Cr14.2Si1.4, negative(NN) is Ni95.5Si4.4Mg0.1.
SICC can supply Extension and Compensating bare thermocouple wire meet the standard IEC60584 and ASTM E230, The advanced melting skills combined controls the chemical composition to achieve the highest quality products , our produce base has the capacity of 900 tons annual that can meet your comprehensive requirements. whatever the bright annealed or oxidized conditions,all thermocouple conductors are calibrated at our lab ,this includes the testing of EMF, chemical composition,physical and thermoelectric properties before shipment.
