Why CuNi have decreasing resistivity with increasing temperature? (quick ans needed)

  1. Aug 14, 2009 #1
    I've been googling around but i seems not able to find why CuNi have decreasing resistivity when temperature is increased at the range of 20 celcius - 80 celcius. Please enlighten me!

    thanks a bunch!

    That's characteristic of a metal. What are the specifics about CuNi that makes you expect something different?
