Copper Nickel Heating Wire
Nickel-chromium and nickel-chromium-iron alloy wire
Nickel chromium and nickel chromium iron alloy are the most widely used high resistance electric heating alloys. This alloy has high resistivity, good oxidation resistance and wear resistance, good machining performance and welding performance, and high strength at high temperatures. The alloy is suitable for manufacturing heating elements, voltage regulating resistors and braking resistors of various motors in metallurgy, chemical industry, machinery, glass, ceramics, household appliances and other industrial sectors.
Ni Cr Si Ni Si Mg thermocouple wire (N type)
The nickel chromium silicon nickel silicon magnesium thermocouple (N-type thermocouple) is a low metal thermocouple, which is the latest internationally standardized thermocouple. The nominal chemical composition of the positive pole (NP) is: Ni: Cr: Si ≈ 84.4:14.2:1.4, and the nominal chemical composition of the negative pole (NN) is: Ni: Si: Mg ≈ 95.5:4.4:0.1. Its use temperature range is - 200~1300 ℃.
Nickel chromium copper nickel (constantan) thermocouple wire (type E)
Nickel chromium copper nickel thermocouple (E-type thermocouple), also known as nickel chromium constantan thermocouple, is also a kind of low metal thermocouple. Its positive electrode (EP) is nickel chromium 10 alloy with the same chemical composition as KP. The negative electrode (EN) is copper nickel alloy. Its nominal chemical composition is 55% copper, 45% nickel and a small amount of cobalt, manganese, iron and other elements. The use temperature of the thermocouple is - 200~900 ℃.
Nickel chromium nickel silicon thermocouple wire (Type K)
Nickel chromium nickel silicon thermocouple (K-type thermocouple) is the low metal thermocouple with the largest usage in the temperature measurement area above 500 ℃, and its usage is the sum of other metal thermocouples. The nominal chemical composition of the positive pole (KP) is Ni: Cr ≈ 90:10, and the chemical composition of the negative pole (KN) is Ni: Si ≈ 97:3, and its operating temperature range is - 200~1300 ℃.
Alloy wire of compensating wire for thermocouple
The function of the thermocouple compensation wire is to extend the thermoelectric electrode, that is, to move the cold end of the thermocouple, and to connect with the display instrument to form a temperature measurement system. The operating temperature is - 25~200 ℃.
