Debonded, Debonding. The separation of an outer clad layer of metal either before or after striking. It is caused by poor adhesion during the bonding process. On a struck piece debonding is considered a clad metal anomaly because of the incorrect preparation of the strip and planchet. It would be described in numismatic literature as a lamination error. The purposeful debonding (as with skeleton scrap) to recycle the metal is accomplished by heating the clad strip to a specific temperature, holding the metal at that temperature until the bond weakens, then physically pulling apart the separate layers.
