Electrical industryElectric power transportationForce transmission need to consume a lot of high conductivity copper. It is mainly used for power wire and cable, busbar, transformer, switch, connect in components and couplings etc..In the transmission of wire and cable, the electric energy of the waste heat is wasted due to the fever of resistance.. From energy saving and economic point of view, the current world is promoting the best cable cross-section standard. The epidemic is over standard, simply from lower installed at one time investment perspective, in order to minimize the cable section, under the rated current of the design requirements, not to appear at risk of overheating to determine cable lowest allowable size. According to this standard cable, although the installation fee is low, but in the long-term use of the process, the resistance energy consumption is relatively large. The best cable section "" standard, taking into account the installation cost and power consumption of these two factors, the appropriate size of cable to achieve energy saving and the purpose of the best comprehensive economic benefits. According to the new standard, the cable cross section is often more than one times than the old standard, can get about 50% energy saving effect.In China in the past period of time, due to shortage of steel, to account for 30% of the proportion of aluminum only copper, in the hope to reduce the weight of the high voltage overhead transmission line has taken measures to aluminum and copper. Underground cable. In this case, aluminum and copper, has the disadvantages of poor conductivity and large size of the cable, and be inferior by comparison.The same reason to energy-saving efficient copper winding transformer, replacing the old aluminum winding transformer, is also a wise choice.

Electronics industryElectronics industry is a new industry, in its flourishing development process, and constantly develop the tapping of the new products and new applications. Its application has been developed from the electro vacuum device and the printed circuit to the microelectronic and semiconductor integrated circuits..Vacuum deviceElectric vacuum device is mainly high-frequency and UHF transmitting tube, waveguide, magnetron. They need high purity oxygen free copper and dispersion strengthened copper oxygen.Transportation industryA shipDue to good corrosion resistance in sea water, many of the copper alloy, such as: aluminum bronze, manganese bronze, brass, aluminium Gunmetal (zinc tin bronze), white steel and copper nickel alloy (Monel alloy) has become standard material for shipbuilding. The weight of the ship and the merchant ship, copper and copper alloys accounted for 3% ~ 2. The ships and the bulk of the large ships are made of aluminum bronze or brass.. The ship's propeller each weight 20 ~ 25 tons. Elizabeth queen number and queen Marie of the aircraft carrier's spiral each weighing 35 tons. The ship heavy tail shaft used "" admiral "" gunmetals, rudder and propeller cone bolt with the same material. The engine and boiler room are also heavily used in steel and copper alloys. The world's first nuclear powered ship, using 30 tons of condenser tubes. Large heating coil with aluminum yellow copper tube as oil tank, there are 12 such tanks in the 100000 ton ship, the corresponding heating system is quite large. Electrical equipment on the ship is also very complex, engine, motor, communication system, etc. almost exclusively rely on copper and copper alloy to work. The size of the ship's cabin often with steel and copper alloy to decorate. And even wooden boats, and the best steel alloy (usually silicon bronze) screws and nails to fix the wood structure, this screw can be used to roll over a lot of production. In order to prevent hull is affecting navigational sea biofouling, often using coated copper protected, or brush copper containing paint approach to the problem.In the Second World War. For the Royal anti German magnetic mines of ship attack, had developed anti magnetic mine device, in the steel hull attached to a circle around the copper, current and ship's magnetic field, so that you can not detonate mines. From 1944, the Allied vessels, a total of about 18000, are equipped with the magnetic device and protected. Some large ships are required to use a lot of copper, such as one of them used to go to copper wire 28 miles, weighing about 30 tons.Light industryLight industry products and people's lives are closely related, variety, variety. Because copper has good comprehensive properties, it can be seen everywhere display one's skill to the full. Now, for example, the number is as follows:Air conditioning and refrigeratorThe temperature control effect of air conditioning and refrigerator, mainly through evaporation and condensation heat exchanger tube to achieve. The size and heat transfer performance of heat exchange heat exchange tubes largely determines the efficiency and the miniaturization of the whole air conditioner and the cooling device.. The special brass tubes with high heat conduction performance are used in these machines.. Steel with good processing performance, development and production of a groove and a high fin heat pipe, used in the manufacture of air conditioning, freezer, chemical and heat collection device of heat exchanger, so that the overall heat transfer coefficient on the new type heat exchanger to use common pipe 2 ~ 3 times, and with ordinary low finned tube 1.2 ~ 1.3 times, has been in the domestic use, can save 40% of copper, and the volume of heat exchanger size cut in 1 / 3 more.
