    High Quality Karma Nickel Based Alloy Foil Corrosion Resistant Heating Strip

     

    1. Karma alloy

    Karma alloy is made up of copper, nickel, Aluminum and Iron as the main components. The resistivity is 2~3 times higher than MENTONG. It has lower temperature coefficient of resistance(TCR), lower thermal EMF versus copper, good permanence of resistance for a long period of time and strong anti-oxidation. Its working temperature range is wider than MENTONG (-60~300ºC). It is suitable for making fine precision resistance elements and strain.

    2. Distinctive features of Karma resistance wire

    1) Starting with Nickel Chromium electric heat wire Class 1, we replaced some of the Ni with
    Al and other elements, and thus achieved a precision resistance material with improved
    resistance temperature coefficient and heat electromotive force against copper.
    With the addition of Al, we have succeeded in making volume resistivity 1.2 times greater
    than Nickel Chromium electric heat wire Class 1 and the tensile strength 1.3 times greater.

    2) The secondary temperature coefficient β of Karmalloy wire KMW is very small, - 0.03 × 10-6/ K2,

    and the resistance temperature curve turns out to be almost a straight line within a wide
    temperature range.

    Therefore, the temperature coefficient is set to be the average temperature coefficient between
    23 ~ 53 °C, but 1 × 10-6/K, the average temperature coefficient between 0 ~ 100 °C, also may
    be adopted for the temperature coefficient.

    3) Electromotive force against copper between 1 ~ 100 °C is also small, below + 2 μV/K, and

    exhibits excellent stability over a period of many years.

    4) If this is to be used as a precision resistance material, low temperature heat treatment is
    required to eliminate processing distortions just as in the case of Manganin wire CMW.
