CHEMICAL COMPOSITION

CHEMICAL COMPOSITION

Elements
Cu(1,2,3) O
(1) Cu is determined by the difference between the impurity total and 100%.
(2) 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.
(3) Cu value includes Ag.
