C11000 Electrolytic Tough Pitch (ETP) Copper
Atlas carries C11000 Electrolytic Tough Pitch (ETP) Copper in Sheet / Plate, Rod & Rectangle (Square Edge). We carry a very large range of sizes and will cut the material to length.
C11000 Electrolytic Tough Pitch (ETP) Copper is produced by the direct conversion of selected refined
cathodes and castings under carefully controlled conditions to prevent
contamination of the pure oxygen-free metal
during processing. The method of producing OFHC copper ensures an extra high grade of metal with a copper content of 99.99%. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree.
This is the most common copper. It is universal for electrical applications. ETP material has a minimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has 0.02% to 0.04% oxygen content (typical). Most ETP copper sold today will meet or exceed the 101% IACS specification. As with OF copper, silver (Ag) content is counted as copper (Cu) for purity purposes.

(1) Cu value includes Ag.
Note: This is a high-conductivity copper which has, in the annealed condition a minimum conductivity of 100% IACS except for Alloy C10100 which has a minimum conductivity of 101% IACS.
Note: Oxygen and trace elements may vary depending on the process.
