Meaning it's been kept melted for a while in a sealed vessel with a charcoal cover on the melt, which draws the oxygen out of the metal. See
here. I would imagine you could do the same thing in an open vessel if you used one of the welding "shield" gasses.
Any idea if low-oxygen copper has higher heat conductivity than the "standard stuff"? I would guess
not just based on the fast that it hasn't become a marketing thing for the heatsink manufacturers.
Note I am not a metallurgist or even metal worker, other than annealing head gaskets and brazing frame tubes in a motorcycle shop a
very long time ago...
