C110 Copper, also known as Electrolytic Tough Pitch, is 99.90% pure copper. ETP 110 is one of the most commonly used commercially pure coppers. C11000 copper has one of the highest electrical conductivity ratings, in excess of 100%IACS. ETP C110 copper also has exceptional thermal conductivity and demonstrates good corrosion resistance. C110 ETP copper has a wide range of uses, including applications in architectural, industrial, electrical, automotive and construction industries.
Marmetal stocks C11000 ETP Copper in Plate, Sheet, Strip, Coil, Pipe and Bar forms.
