Maybe there's a thermally ideal lattice arrangement for copper we can get by by adding some impurity. Maybe.

Look up the reasons why sugar with do that.
We are talking about 2 ingredients not a combination of many. The properties of each are known as is the process on how they are combined and we now know the outcome. We can break down what benifit/disadvantage the 28% copper added in thermal conductivity in the process they use to make the stuff.
Silver is 418
Copper is 388
CuSil is 371
Adding copper to silver actually had a negative effect. Figure that one out....
