Material Name: Professional production and sales GB Environmental copper row, copper rods, copper, copper plate, copper strip, copper wire Material: T1, T2, T3, TU1, TU2, TP1, TP2, C1011, C1020, C1100, C1201, C1220, C1221 and so on. 3. Material characteristics: Have good electrical conductivity, thermal conductivity, corrosion resistance and workability, welding and brazing can. Including lower electrical conductivity, thermal conductivity less impurities, traces of oxygen has little effect on conductivity, thermal conductivity and processing performance, but easy to cause a "hydrogen disease", not processing (annealing at high temperatures (eg> 370 ℃) reducing atmosphere, welding, etc.) and use. Often contain oxygen, sulfur, lead, arsenic, bismuth, phosphorus and other impurities. With excellent electrical conductivity, thermal conductivity, moderate mechanical properties. It can be used for the preparation of copper alloys and alloying elements. Widely used in the field of electrical appliances electrician for electrical and thermal conductivity material. Smelting of copper, refined copper electrolysis reflecting furnace fire method. Preparation or sources: natural important copper chalcopyrite, chalcocite, cuprite and malachite, etc., but are low grade. Sulfide ore to be calcined coke sulfur dioxide and a small amount of crude copper eutectic, and then reduced to blister copper, and finally electrolysis refining derived. Copper trace impurities have a serious impact on the electrical conductivity, thermal conductivity of copper. Which significantly reduces titanium, phosphorus, iron, silicon and other electrical conductivity, and cadmium, and zinc is little effect. Oxygen, sulfur, selenium, tellurium and other solid solubility in copper is very small, and can generate a brittle compound of copper, has little effect on the conductivity, but can reduce the processing of plastic. Ordinary copper heated hydrogen or carbon monoxide reducing atmosphere, hydrogen or carbon monoxide, easy and cuprous oxide grain boundaries (Cu2O) effect, generating high pressure steam or carbon dioxide gas, copper can rupture. This phenomenon is often called copper "hydrogen disease." Oxygen copper welding harmful. 4. Scope: The use of copper is much more extensive than pure iron, each year 50% of copper is electrolytic purification of copper, for the electrical industry. Here, the copper, really have to be very pure copper over 99.95% of the job. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Copper oxygenated (easily mixed with a small amount of oxygen when copper) on a large conductivity for electrical industry generally must be oxygen-free copper. In addition, lead, antimony, bismuth and other impurities in crystals of copper will not combine to cause heat brittle, will also affect copper processing. This high purity copper, general electrolysis refining: the non-copper (ie blister) as the anode, copper as the cathode, with LS copper solution as electrolyte. When the current through the impure copper anode gradually melting, copper will gradually deposited on the cathode. Such refining of copper; purity of 99.99%. Copper is a comparison of pure copper, copper is generally considered to be approximate, electrical conductivity, have good ductility, but the strength and hardness of some poor. 5.
