<p>A method for using a copper and an aluminium alloy in cooperation. In the method, an oxide layer (the oxide layer is very thin and has a very low resistance) of a copper and aluminium alloy body is kept as an isolation protection layer to prevent an electrochemical reaction; the copper cooperates with the aluminium alloy (such as an aluminium magnesium alloy and a rare earth aluminium alloy) in an overlapping bond; and two conductors which are relatively independent but have the same electrical potential are formed by the copper and aluminium alloy through the disintegration of the isolation protection layer, so that there will be no electromagnetic interference therebetween, the distribution of the current density is uniform, and the effect is greatly improved. The method for using the copper and aluminium alloy in cooperation is applicable to conductors of electric wires and cables, buses, transformers, switches and sleevings of various voltage classes.</p> |
