Bimetallic Sheet and Plates. Bimetal Consists of Copper(Sheet metal) cladded on pure Aluminum(Base metal), both metal being diffused together to form an inseparable whole by rolling bonding process.

Bimetallic copper and aluminum washers are used to reduce galvanic corrosion between metal parts of different nature causing corrosion phenomenon. The contact between material such assteel/copper, aluminium/copper ou zinc/copper generates an electrochimical reaction that leads to an electrolytic corrosion.

The most renowned type of bi metals are bimetallic sheets: this product has two sheets of different metals “bonded” together, by means of a high-pressure compression and rolling process, which allows the two layers to adhere perfectly to the adjacent sides.

Bimetallic washers place between the grounding/equipotential clamp, such as earth clamps, cable holders or flexible earthing braids, and steel surface onto which they are mounted, reduce the corrosion effect while providing an electrical continuity.
