Summary:A process for separating the clad layer from the core of brazing sheet and which comprises heating the sheet until the clad layer becomes liquid or semi-liquid but the core remains solid, removing the clad layer in its liquid or semi-liquid state and then recovering the same, and wherein the said clad layer is removed by mechanical means which apply a shear force directly to the clad layer. The process enables the economic and efficient recovery for recycling purposes of the core alloy and/or the cladding alloy from brazing sheet scrap.
