Need help w/metal properties

  1. Dec 4, 2008 #1
    Does anyone know a website that I can get coefficient of resistance of metals?
    I've been searching for 2 weeks and have yet to get more than a few basic material readings, "alpha" per degree Celsius. (example) Nickel 0.005866 is there any metal larger than that number?

    Nickel's TCR is the largest I've seen on a list of about twenty-five common elements. The value is similar for the other elements in that group, iron and cobalt. Most other metals are lower, around 0.4%/K.

    The list came from here.

    It's striking how much the values differ between the multiple lists, though the order of magnitude is the same. A reminder of how exquisitely sensitive resistivity is to sample purity. Note the good agreement, though, for platinum, due to both extensive characterization as a temperature sensor (in RTDs) along with limited impurity incorporation into a noble metal.
