What Is C11000 Copper

The c11000 control is T2 and is a material.

C11000 is named for its purplish red color. See copper for various properties. Purple copper is industrial pure copper, its melting point is 1083 ℃, no isotopic transformation, relative density of 8.9, five times that of magnesium. About 15% heavier than ordinary steel. It has a rose-red color, the surface is purple after the formation of oxide film, so it is generally known as purple copper. It is a copper containing some oxygen, and therefore also known as oxygen-containing copper.C11000 has good electrical and thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. Containing reduced electrical conductivity, thermal conductivity impurities, trace amounts of oxygen on the electrical conductivity, thermal conductivity and processing performance impact is not significant, but easy to cause "hydrogen disease", should not be processed at high temperatures (such as > 370 ℃) in a reducing atmosphere (annealing, welding, etc.) and use.
Here the copper, indeed to be very pure, containing copper 99.95% or more. Very small amounts of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Oxygen in copper (copper refining is easy to mix a small amount of oxygen) has a great impact on the conductivity, copper used in the electrical industry are generally oxygen-free copper. In addition, lead, antimony, bismuth and other impurities will make the copper crystallization can not be combined together, resulting in thermal embrittlement, will also affect the processing of pure copper. This very high purity of pure copper, generally refined by electrolysis: the impure copper (i.e., crude copper) as the anode, pure copper as the cathode, with copper sulfate solution as the electrolyte. When the current passes, the impure copper on the anode gradually melted, pure copper will gradually precipitate on the cathode. The copper refined in this way; the purity can reach 99%.

C11000 Physical Properties:

Tensile strength σb (MPa): ≥275

Elongation δ10 (%): ≥5 Elongation δ5 (%): ≥10

C11000 is easy to produce hydrogen embrittlement in the reduction medium containing hydrogen, commonly known as hydrogen disease, so it is not suitable for processing and use in the reduction medium at high temperatures of 370 degrees Celsius and above: in the low-250 degrees Celsius below, its strength will improve.

C11000 is cathodic remelted copper, which has high electrical and thermal conductivity, good corrosion resistance and processing performance, can be fusion welding and brazing.

C11000 is mainly used as a conductive, thermally conductive and corrosion-resistant components, such as wires and cables, conductive screws, housings and a variety of conduits and the aerospace industry.
