Cladding Process

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.

Cladding Process

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.
