C11000 Pure copper

C11000 Pure Copper is a purple red metal, commonly known as "red copper". It is malleable. It as the size of a drop of water can be pulled into filaments up to two kilometers long or rolled into almost transparent foil larger than a bed. The most valuable property of C11000 is that it conducts electricity very well, so it has become the "leading role" of the electrical industry.

The applications of C11000 is much more extensive than iron, 50% of Cu is purified into pure copper by electrolysis every year, used in the electrical industry. Normally very small amounts of impurities, such as phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Oxygen in copper (copper smelting is easy to mix with a small amount of oxygen) also has a great impact on conductivity, so the Cu used in the electrical industry must generally be oxygen-free copper. In addition, lead, antimony, bismuth and other impurities will make the crystallization of copper can not be combined together, resulting in hot brittle, will also affect the processing of C11000.

This kind of copper with high purity is generally refined by electrolysis: the impure copper (coarse copper) as the anode, C11000 as the cathode, and copper sulfate solution as the electrolyte. When the current passes through, the impurity copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. Copper obtained by such refinement; The purity can reach 99.99%.

Copper has good electrical conductivity and great plasticity.
