Products Description
C11000 Electrolytic Tough Pitch (ETP) Copper is known for its high electrical and thermal conductivity, good corrosion resistance and solderability. C11000 copper is used for welding fixtures, anodes, bus bar in electrical power installations, ground straps, commutators and current-carrying hardware. Its inherent fabrication qualities readily permit it to be bent, soldered, drilled, peened, riveted and formed to fit almost any design specification. This copper has excellent hot workability.
