Copper Pipe, Oxygen-free copper tube (OFC), C10100 (OFHC) Oxygen Free High Conductivity Copper Tube

1, Product Name

Copper Pipe, Oxygen-free copper tube (OFC), C10100 (OFHC) Oxygen Free High Conductivity Copper Tube

2, Short Introduction of Copper Tubes：

3, Production Details  of Copper Tubes:

Oxygen-free copper (OFC) or Oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrically refined to reduce the level of oxygen to 0.001% or below. Oxygen-free copper is a premium grade of copper that has a high level of conductivity and is virtually free from oxygen content. The oxygen content of copper affects its electrical properties and can reduce conductivity.

The C10100 Oxygen Free High Conductivity Copper (OFHC) Tubing produced by Womic Copper Industrial are in a wide range of sizes, diameter, wall thickness, length, all can be customized.

C10100 OFHC 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.

4, Characteristics of OFHC copper are: 

A Impurity maximums in ppm of C10100 shall be: antimony 4, arsenic 5, bismuth 1.0, cadmium 1, iron 10, lead 5, manganese 0.5, nickel 10, phosphorus 3, selenium 3, silver 25, sulfur 15, tellurium 2, tin 2, and zinc 1.

B C10400, C01500, and C10700 are oxygen-free coppers with the addition of a specified amount of silver. The compositions of these alloys are equivalent to C10200 plus the intentional addition of silver.

C C11300, C11400, C11500, and C11600 are electrolytic tough-pitch copper with silver additions. The compositions of these alloys are equivalent to C11000 plus the intentional addition of silver.

D Copper shall be determined by difference between “impurity total” and 100 %.

E Copper (includes silver) + phosphorus, min.

F Values are minimum silver in troy ounces per avoirdupois ton (1 oz/ton is equivalent to 0.0034 %).

The specification number shall be shown when specified.

7, Oxygen-free Copper tube applications:

On industrial applications, oxygen-free copper is valued more for its chemical purity than its electrical conductivity. OF/OFE-grade copper is used in plasma deposition (sputtering) processes, including the manufacture of semiconductors and superconductor components, as well as in other ultra-high vacuum devices such as particle accelerators. By the role of conveying current and connecting electrical equipment, Solar photovoltaic project construction, Substation project construction material. Superior Audio/Visual Applications, High vacuum applications,

Large industrial transformers – the increased electrical conductivity of Oxygen Free Copper can reduce the diameter of the wiring within transformers and therefore reduce the amount of copper and the size of the overall installation.
