在我国电子、邮电、航天等领域中,每年消耗着大量的白银和钢材。本文通过电气、化学、焊接和抗磨性能等多种试验和研究以及各种科学论证和分析,说明是可以部分或大部分采取以铜代银,以铝代铜,实现节省白银和铜材等贵重金属的,并提出了具体的节省途径和方法。这一目的在我国的实现将会产生巨大的经济效益,对保护贵重矿物资源有着深远的战略意义。
In our country’s electronics, post and telecommunications, aerospace and other fields, each year consumes a large amount of silver and steel. This article through a variety of tests and studies of electrical, chemical, welding and anti-wear properties and a variety of scientific evidence and analysis shows that can be taken in part or most of the copper on behalf of silver to aluminum on behalf of copper, silver and copper to save money Precious metals, and put forward specific ways and means of saving. The realization of this goal in our country will have tremendous economic benefits and will have far-reaching strategic significance for the protection of precious mineral resources.
