Product Description
Product Description
  • Constantan has a low temperature coefficient of resistance (TCR), and a wide operating temperature range (below 500 degrees C). It has good properties on mechanical working, high resistance of corrosion. Constantan wire used for variable and strain resistance elements in alternative instruments
  • Constantan chemical composition:
    • Cu： Bal
    • Mn: 1-2%
    • Ni: 39-41%
  • Standard： GB/T6145-2010
  • Constantan properties:
    • (20 degrees C) resistivity: 0.48±0.03 μΩ.m
    • (20 degrees C) temperature coeff. of resistance： ≤±40αX10-6/degrees C
    • (0-100 degrees C) thermal EMF vs. copper： 45μv/degrees C
    • Maximum working temperature： ≤500 degrees C
    • Elongation： ≥15%
    • Tensile strength： ≥390N/mm2
