(1) Cu is determined by the difference between the impurity total and 100%.
(2) Cu value includes Ag.
(3) In troy ounce: Min = 25, Max = 0 and Nom = 0
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.
