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 |
