Today's new information recommends that copper is industrial pure copper C1100 copper wire.
C1100 got its name from the fact that it is purplish red. Various properties are seen in copper. Copper is industrial pure copper, its melting point is 1083, no allotrope transition, and the relative density is 89, five times that of magnesium. It is about 15% heavier than regular steel.
C1100 has a rose red color, and the surface is purple after forming an oxide film, so it is generally called copper. It is copper that contains a certain amount of oxygen, so it is also called oxygenated copper. C1100 has good electrical, thermal, corrosion and processing properties and can be welded and brazed. It contains less impurities that reduce electrical conductivity and thermal conductivity, and a trace amount of oxygen has little effect on the properties of electrical conductivity, thermal conductivity and processing, but it is easy to cause "hydrogen disease", and it is not suitable for processing (annealing, welding, etc.) in a reducing atmosphere at high temperature (such as 370) and use.
The copper mentioned here is indeed very pure, and C1100 contains 99 copperMore than 95% is required. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., can greatly reduce the electrical conductivity of copper. The oxygen content in copper (a small amount of oxygen is easy to be mixed when smelting copper) has a great influence on the electrical conductivity, and copper used in the electrical industry generally must be oxygen-free copper. In addition, impurities such as lead, antimony, and bismuth will make the crystals of copper unable to bind together, resulting in hot embrittlement, which will also affect the processing of pure copper. This kind of pure copper with high purity is generally refined by electrolysis: impure copper (i.e., blister copper) is used as the anode, pure copper is used as the cathode, and copper sulfate solution is used as the electrolyte. When the current passes, the impure copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. Copper obtained by such refining;The purity can reach 99%.

C1100 is prone to hydrogen embrittlement in hydrogen-containing reducing medium, commonly known as hydrogen disease, so it is not suitable for processing and use in reducing medium with a high temperature of more than 370 degrees Celsius: its strength will be increased below -250 degrees Celsius.
C1100 is cathode remelted copper, which has high electrical and thermal conductivity, good corrosion resistance and processability, and can be fusion welding and brazing.
C1100 is mainly used as electrically conductive, thermally conductive and corrosion-resistant components, such as wires and cables, conductive screws, housings and various conduits and aviation industry.
