https://www.copper.org/publications/pub_list/pdf/a1360.pdf Please refer 
to this "most excellent" publication on "Copper"! After reading all 
about the research of others on this site, I would venture to guess that 
90% of you folks do not realize the "improved performance" of coils etc. 
if you would just  "anneal" to get the maximum "conductivity"!  Pure 
99.99 copper in a full "dead soft" annealed condition (after forming 
your device) will yield almost "super conductivity" at room 
temperatures!  Materials handbook (Metallurgy) shows what happens to 
copper molecular structure after annealing!  They call it "puffing up" 
the copper by loosening the atomic bonds.  Warren! works great on those 
copper head gaskets!  Lol
