Overlay Cladding – Bonding of Up to 5 Dissimilar Material Layers
Overlay cladding is a process by which up to 5 dissimilar layers of material are bonded together through a cold bonding process. This process creates products with multiple performance advantages. The cladding of multiple metals into a single composite strip can provide the desired properties unique to a specific application.
As an example, a material system can be designed and manufactured using one material on the surface for corrosion resistance, weld ability or other benefits and a different core material for other specific properties such as thermal properties, electrical conductivity, and strength.
Benefits of Metal Overlay
| Clad Combination | Benefit | Application |
|---|---|---|
| Cu/Steel/Cu | Conductivity/Strength/Cost | Fuse clips, spring contacts Structural Strength with Electric & Thermal conductivity |
| Cu/Stainless/Ni | Conductivity/Strength/Corrosion | Cell Batteries |
| Ni/Stainless/Ni | ||
| Cu/Al | Cost; Weight; low contact resistivity; Thermal Characteristics | High current carrying conductors, Busbars |
| Cu/ Ni or Ni/Cu/Ni | Thermal; Weldability; Formability | Li- Ion Battery |
