A roll-clad composite is a composite material that consists of several different layers of metal. The metal layers may be clad in various thicknesses. The individual layers of a roll-clad composite material are inseparably joined.
An advantageous combination of materials will lead to different properties that can not be achieved with the individual materials alone.
1. CIC (copper-invar-copper)
- The invar foil is the core material that is clad on both sides with a copper foil.
- Application areas include special circuits, metal cores and heat sinks.
- The composite foil can be provided without having been treated (uncoated).
- To improve the bond and/or peel strength of laminates, by request our CIC foils undergo a single or double-sided Cu treatment or Cu/Zn treatment.
2. Silvered copper, roll-clad (Cu/Ag)
- The good conductivity of the copper is combined with silver`s high gloss.
- In addition, the silver surface offers good protection from corrosion.
3. Tinned copper, roll clad (Cu/Sn)
- Various tin and tin-solder layers are available.
