C11000 is Electrolytic tough pitch copper C11000 is made from cathode copper, that is, copper that has been refined electrolytically. C11000 is the most common of all the electrical coppers. It has high electrical conductivity, in excess of 100% IACS.
Produced in all forms except pipe and used for building fronts, down-spouts, flashing, gutters, roofing, screening, spouting, gaskets, radiators, busbars, electrical wire, stranded conductors, contacts, radio parts, switches, terminals, ball floats, butts, cotter pins, nails, rivets, soldering copper, tacks, chemical process equipment, kettles, pans, printing rolls, rotating bands, roadbed expansion plates.
