CHEMICAL COMPOSITION

Elements
Cu(1,2,3) Pb Zn Fe P Ag As O Sb Te
(1) 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.
(2) Cu is determined by the difference between the impurity total and 100 %. For alloy C10100 the Cu value is exclusive of Ag.
(3) The following additional impurity maximum limits shall apply: Bi 1ppm (0.0001%); Cd 1ppm (0.0001%); Mn 0.5ppm (0.00005%); Ni 10ppm (0.0010%); Se 3ppm (0.0003%); S 15ppm (0.0015%); Sn 2ppm (0.0002).
