IIRC, Viborg uses what they call red copper, which is probably red brass - a high Cu content brass, quite a bit harder than pure Cu. Visually and under a few strokes of a metal saw (I wanted to check if this is not a plating) behaves indeed like a 'hard copper'. I protect the surfaces I can reach using Paul's method (I 'hate' you for that Paul, takes so much time): jewellery polish (me by hand) - isoprop cleaning - dielectric grease (silicon based DC-4)


If Viborg is following the market standards and I think so, "Red Copper" or "Pure Red Copper" is Cu2O, the first stage of the Copper Oxide. But I don't remember of anything about red copper on Vigorg literature except, may be, on power cables.
