C11000 Electrolytic Tough Pitch (ETP) Copper Rod or Solid Bar. 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 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 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 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.

TYPICAL USES

Some of the typical areas that C11000 is used in, is as follows:

Building Fronts, Gutters, Skylight Frames, Roofing, Flashing, Downspouts, Spouting

Pressure Vessels, Chemical Process Equipment, Chlorine Cells, Chimney Cap Screens, Heat Exchangers, Printing Rolls, Anodes, Rotating Bands, Kettles, Pans, Vats, Road Bed Expansion Plates

CHEMICAL COMPOSITION

(%max., unless shown as range or min.)

(1) Cu value includes Ag.

Note: This is a high conductivity copper which has, in the annealed condition a minimum concuctivity 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.
