What is C11000 copper?
C11000 copper is used for welding fixtures, anodes, bus bars in electrical power installations, ground straps, commutators, and more. Its inherent fabrication qualities readily permit it to be bent, soldered, drilled, peened, riveted and formed to fit almost any design specification. Class 11000 copper is specified because of its high thermal and electrical conductivity.

C10100 vs C10200 vs C11000
All three are grades of pure copper. C10100 is produced under the strictest controls with a nominal purity of 99.99%, C10200 is slightly lower purity at 99.95%, with C11000 being the lowest purity at 99.9%. The increased purity offers more reliable electrical performance over a wide range of service conditions. The most specific drawback is the potential of C11000 to suffer from high temperature hydrogen embrittlement due to the presence of oxygen in the copper.
