Sheets and Washers for Copper- Aluminium Connections

 Bimetal plate and washer are used in connect betwen copper and aluminum conductors . in order to avoid crossion and make the connector ineffetive and unreliable .

Being Cu and Al material with diffrent electical potential , the contact between the two aterial a galvanic cell in presence of an electrolyte , with deterioration if the aluminum material with rapid decay of electrics capacitance .f the contact surface(Stack effect).

The most important is the bi metallic  Cu-Al sheet or washer prevents the on set of the problem . sine the products are bimetallic (obtained by explosion welding ) the Cu And Al surface are moleclarly connected , with out the presence if the electrolyte thant could be trigger.
