Description:

the copper rod is named for its purplish red color. It is not necessarily pure copper and is sometimes added in small amounts of deoxidized elements or other elements to improve material and properties and is therefore also placed in copper alloys. The processed materials of Chinese red copper can be divided into four categories according to their composition: common red copper (T1T2T2T3T3T4), oxygen free copper (TU1T1TU2) and high purity, vacuum oxygen free copper, deoxidized copper (TUPU TUMnN), and special copper (as copper, tellurium copper, silver copper) with a small amount of alloying elements. Copper conductivity and thermal conductivity second only to silver, widely used in the manufacture of conductive, thermal equipment. Copper has good corrosion resistance in atmosphere, sea water and some non-oxidizing acids (hydrochloric acid, dilute sulphate, alkali, salt solution and various organic acids (acetic acid, citric acid). It is used in chemical industry. Good electrical conductivity, heat conduction, corrosion resistance and processing performance, soldering and brazing. It contains lower conductivity, less thermal conductivity impurity, and trace oxygen has little effect on conductivity, thermal conductivity and processing properties, but it is easy to cause “hydrogen sickness”, which is not suitable for processing (annealing, welding, etc.) in the reductive atmosphere at high temperature (such as > 370 ℃).

Characteristics:

high purity, fine tissue, very low oxygen content. No porosity, trachoma, loose, excellent electrical conductivity, high surface accuracy of electroetching mould, heat treatment technology, no direction of electrode, suitable for fine beating, good thermoelectric, processability, ductility, Corrosion resistance and weathering.

Role:

Copper bars are used more widely than pure iron. 50% of copper is electrolyzed to pure copper each year for use in the electrical industry. The copper in question really needs to be very pure and contains more than 99.95% copper. A very small amount of impurities, especially phosphorus, arsenic, aluminum and so on, will greatly reduce the conductivity of copper. Oxygen in copper (which is easy to be mixed with a small amount of oxygen in copper smelting) has a great influence on conductivity. Copper used in electrical industry must be oxygen free copper. In addition, lead, antimony, bismuth and other impurities will make copper crystal can not be combined, resulting in hot brittle, will also affect the processing of pure copper. This kind of pure copper with high purity is usually refined by electrolysis: using pure copper as anode, pure copper as cathode and copper sulfate solution as electrolyte. When the current passes, the impure copper on the anode gradually melts and the pure copper is precipitated on the cathode. Copper so refined; purity up to 99.99. Red copper is a kind of copper which is relatively pure, which can be considered as pure copper. Its electrical conductivity and plasticity are better, but its strength and hardness are worse.
