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 celsius - 80 celsius. Please enlighten me!

thanks a bunch!

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


basically none. I am finding some. well thanks anyway. problem solved!
