Bimetal plates and washers are used for connections between copper conductors and aluminium one's, in order to avoid corrosion that makes connection ineffective and unreliable.
The interposition of a bimetallic Cu-AL plate or washers prevent the onset of the problem: since these products are bimetallic (obtained by explosion welding), the copper and aluminium surfaces are molecularly linked, without the presence of an electrolyte that can trigger the galvanic corrosion.
