Isn't pure copper more thermal-conductive than .925 silver?

https://en.wikipedia.org/wiki/List_of_thermal_conductivities
It says that pure copper has higher thermal conductivity than .925 silver, is that true?
Alloy usually have lower thermal conductivity than pure metal, so what's the point of .925 silver?

coatings on copper usually have the background to protect the material.
my modest opinion. Copper runs over time. it becomes darker and often green and bumpy.
for pc components now not quite as bad but still possible.
So I do not believe it is the temperature recording silver vs. Copper goes. rather around silver vs. nickel on copper. ....

my English is for the ass ;) Google helps

Pure copper is extremly oxidative. It would be the nonplusultra material for thermal dissipation but it would pretty much solder itself in short time to its adjacent materials :D

Copper is why the statue of liberty is green. Diamond would work, but too bad one company controls the world's supply.
