Why is Cu-Zn alloy conductivity less than conductivity of pure copper?
Why is Cu-Zn alloy conductivity less than conductivity of pure copper?
Homework Answers
Cu-Zn electrical conductivity is less than pure Cu conductivity
, because we know pure copper have more conductivity than pure Zn
conductivity
When Cu-Zn alloy is formed some copper metal is removed by Zn so Zn
is taking position of Cu , so Zn is less conductivity so overall
Cu-Zn conductivity alloy is less than pure Cu.
