Our company aims to be the best-quality alloy producer in the world.We insist on developing the more advanced alloy strip technology, to serve all the customer, improve people's living level,make a more green earth in the future.
4.MAIN CHARACTERISTICS OF OUR THERMOCOUPLE ALLOYS
TYPE JÂ (Iron vs Constantan) is used in vacuum, oxidizing, inert or reducing atmospheres.Iron element oxidizes rapidly at temperatures exceeding 538'C, and therefore heavier gauge wire is recommended for longer life at these temperatures.
TYPE KÂ (CHROMEL vs ALUMEL )Â is used in oxidizing, inert or dry reducing atmospheres.Exposure to vacuum limited to short time periods.Must be protected from sulfurous and marginally oxidizing atmospheres.Reliable and accurate at high temperatures.
TYPE TÂ (Copper vs Constantan) is used or service in oxidizing, inert or reducing atmospheres or in vacuum.It is highly resistant to corrosion from atmospheric moisture and condensation and exhibits high stability at low temperatures.It is the only type with limits of error guaranteed for cryogenic temperatures.
TYPE E (CHROMEL vs Constantan) may be used in oxidizing, inert or dry reducing atmospheres, or for short periods of time under vacuum.Must be protected from sulfurous and marginally oxidizingatmospheres.Produces the highest EMF per degree o any standardized thermocouple.
Type N thermocouple (Ni Cr Si-Ni Si Mg)  is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has.The main chemical composition of positive leg Nicrosil(NP) is Ni:Cr:Si≈84.4:14.2:1.4;Negative leg Nisil (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 °C.
