How Clad Becomes Clad

There are several ways we make clad metals at EMS, yet, the most common method is by a continuous roll bonding process that combines two or more strips of metal.

Cleanliness is paramount.  First, the individual strips are either chemically or mechanically cleaned to provide contaminant-free surfaces. The strips then pass through a highly customized rolling mill which is designed specifically for cladding.

As they pass through the mill, the rolls exert immense pressure that reduces strip thickness and creates a metallurgical bond as the atomic lattices of the different metals merge into a common structure. The resulting composite material – a clad metal – derives its integrity from this shared electron interface.

Heat is then applied to induce diffusion, which improves bond strength and provides stress relief for cold processing. This results in a clad metal devised of precisely the right properties for its specific application. And that is the key benefit of cladding: the ability to combine the most desirable characteristics from different metals into a unique new metal composite that allows you do things you couldn't do before.
