Cu is determined by the difference between the impurity total and 100%. The Cu value is exclusive of Ag. Note: The following additional maximum limits shall apply: Bi, 1ppm (.0001%); Cd, 1ppm (.0001%); Fe, 10ppm (.0010%); Pb, 5ppm (.0005%); Mn, 0.5ppm (.00005%); Ni, 10ppm (.0010%); Se, 3ppm (.0003%); Ag, 25ppm(.0025%); S, 15ppm (.0015%); Sn, 2ppm (.0002%); Zn, 1ppm (.0001%).
Note: This is a high conductivity copper which has, in the annealed condition a minimum conductivity of 100% IACS except for Alloy C10100 which has a minimum conductivity of 101% IACS.
