Electrolytic Tough Pitch Copper (ETP)

ASTM B124, ASTM B152, ASTM B187, ASTM B370, DIN 2.0060, BS 2870 C101, BS 2874 C101, BS 2875 C101, EN CW004A

C11000 Electrolytic Tough Pitch, known as ETP Copper or tough pitch copper, has long been the standard type of commercial wrought copper used in the production of sheet, plate, bar, rod, strip and wire. Although ETP Copper is not 100% oxygen free, it is considered to be an OFC (oxygen free copper) because it has a minimum conductivity rating of 100% IACS while the minimum rating to considered OFC is 99.9% pure. ETP Copper is the most common and widely used copper because of its conductivity. ETP Copper 110 has an extremely wide range of applications based on its conductivity, corrosion resistance, workability, and beauty.
