Regarding the following table:
*********************************************
Gilding metal 31 nano ohm.meter
Aluminum Alloy 1100 29
Aluminum alloy 7072 29
Aluminum 99.99% 27
Gold, pure 25
Gold commercial 23
Copper deoxidized 20
Copper, electrolytic 17
Silver, pure 16 nano ohm.meter
*************************************************************************
(1) Is deoxidized copper the same as OFHC (oxygen-free high conductivity)
copper?
(2) What is electrolytic copper?
(3) What is the resistivity of non-OFHC copper? I was wondering how much
difference the OFHC makes.
