Clad Metals

Premium Quality, Multifunctional Clad Metals

These composite metals are widely applied to automotive electrical and electronic components, EV components, secondary batteries, and mobile phones. These materials, which are fabricated by combining multiple metals, provide the electrical and physical properties that cannot be achieved with a single metal. Thus, these materials can be effectively used in designing multifunctional products and reducing production cost by replacing precious metals.

Clad Metal can be defined as a metallurgical combination (bonding) of two or more metals under high pressure, resulting in a composite piece with the physical and electrical properties that cannot be achieved with a single metal or alloy. According to the types of bonding and materials, CSC’s clad metals are divided into an inlay clad, overlay clad, solder clad, contact tape clad, and composite clad.

Applications
∙ Battery tab, Bus-bar, Switch contact for automotive & home appliance, contact for electric parts.

Inlay Clad

Inlay clad metals are products made by skiving at the base metal and inserting the contact material into a connection through the rolling process. It is possible to implement a property that cannot be achieved by coating. They are also cost effective in design because one only needs to insert the desired number of them into the parts they want.

Applications
∙ Small motor parts, Electric contact switch, home appliance switch and connectors
