C11000
C11000 - Electrolytic Tough Pitch (ETP)
Spec Equivalents: CDA 110 ETP, ASTM B124, ASTM B152, ASTM B187, ASTM B188, ASTM B272
The electrolytic tough pitch copper is the copper with high thermal and electrical conductivity. The products manufactured using this copper possess good corrosion resistance and soldering ability. The inherited fabrication qualities of the copper allows it to bend, drilled, soldered, riveted and to be fit in to almost any design specifications. This variant of copper has excellent hot workability.
