Al-Cu BimetalBimetal Consists of Copper Sheet cladded on pure Aluminum Which is Base Metal alloy , both metal being diffused to form an inseparable whole by rolling bonding process. Bimetal , is therefore not and alloy and copper layers are not electro Plating but are rather mechanically welded Aluminum Plates / Sheet .Bi-Metal of Aluminium and Copper has Different name In different Sector and Country .
