在电气工程中以铝代铜是我国一项具有重大意义的技术经济政策。在耗铜最多的电气工程部门(约占总耗量的2/3),以铝代铜是贯彻“自力更生,独立自主”方针的重大措施之一。然而,要推广以铝代铜、必须要首先解决的一个关键问题是铝—铜简单而可靠的连接问题。 Taking aluminum as substitute copper in electrical engineering is a significant technical and economic policy in our country. In the electrical engineering department that consumes the largest copper (accounting for about two-thirds of the total consumption), taking aluminum as a substitute for copper is one of the major measures to implement the policy of “relying on one’s own efforts and relying on one’s own efforts and becoming independent.” However, to promote copper on aluminum, one of the key issues that must be addressed first is the simple and reliable connection of aluminum-copper.
