would u expect the youngs modulus of an alloy to be higher than that of a pure metal?

Question

i'm comparing the youngs modulus of copper with constantan. constantan is the alloy where copper (as u know) is a pure metal. thing is, i research the youngs modulus for both materials on the net and i got 110 MPa for constantan and 124 GPa for copper. now that i'm calculating the youngs modulus from these graphs i've got from the teacher, constantan is getting the higher youngs modulus as compared to copper.
i know i haven't calculated anything wrong, so thats not a possibility.
so would you expect an alloy to have a higher youngs modulus than a pure metal?

Answer 1

Alloys are usually made to improve on the strength of a metal, so yes.

for instance gold is too soft for most jewelery application, so it is alloyed with silver or copper to make it strong enough to stand up to daily wear and tear.
