废铜回收的重要性铜本身的特点使得其在社会经济发展中的作用无可替带。铜确立了导电率标准,铜由于有出色的载流能力,比其他任何导体的导电性都要优良,因此确立了世界上导电率的标准。铜具有优良的适应性,和铝相比,铜线的适应性更强,建筑用铜导线对绝缘能力和导管的要求比铝导 The Importance of Scrap Recovery The nature of copper itself makes it an irreplaceable role in socio-economic development. Copper sets the standard for electrical conductivity, and copper, because of its excellent current carrying capacity, is superior to the conductivity of any other conductor and therefore sets the standard for electrical conductivity in the world. Copper has excellent adaptability, compared with aluminum, the adaptability of copper wire stronger, the construction of copper wire insulation capacity and the requirements of the catheter than aluminum
