Description

ISAOHM® resistance alloy is a Nickel-Chromium alloy (NiCr20AlSi) offering high resistivity, low-temperature coefficient, low thermal EMF compared to Copper and high tensile strength. It is also resistant to oxidation and chemical corrosion, allowing the working temperature of up to +250°C for precision resistors/current measurement applications (when used for heat generation it can be used for much higher temperatures). ISAOHM® is available in form of round wires from 0.01 to 0.6 mm2 which can be bare, oxidised or enamelled to the highest standard, stranded wires and flat wires.
As with all Isabellenhütte alloys, all manufacturing from the raw material is done at their German plant with state-of-the-art equipment and under continuous testing to achieve a fully tracked manufacturing process. This allows Isabellenhütte to make slight adjustments in order to melt an alloy tailored to a customer’s requirement, such as adjusting the resistivity by special heat treatment. Please see the datasheet in the Technical library, however, do not hesitate to contact us if what you require is not exactly matched.

  • Resistance alloy NiCr20AlSi
  • Low-temperature coefficient of electrical resistance
  • Temperature range of up to +250°C when used for current measurement/resistor applications (higher is used for heat generation)
  • Low thermal EMF compared to Copper
  • Suitable for brazing, welding and can be soldered under certain conditions

 

Typical applications for ISAOHM® resistance alloy include:

  • High-value resistors
  • Potentiometers
  • Automotive industry
  • Consumer electronics
  • Heating cords and cables
