铜是重要物资之一,目前,我国铜的资源十分缺乏,几年来,铜的供应都是紧张的,特别是明年将更加紧张。因此,广泛提倡节约用铜,积极采取有效措施,推行代用材料,以确保急需部门的用铜需要,是保证国民经济建设顺利进行的重要措施之一。 Copper is one of the important materials. At present, the resources of China’s copper are very scarce. In recent years, the supply of copper has been tense, especially in the next year. Therefore, it is widely advocated that the use of copper should be saved, active measures should be taken actively, and the use of substitute materials in order to ensure the need for the copper needed by the urgently needed departments is one of the important measures to ensure the smooth progress of national economic construction.
