Beschreibung
Zusammenfassung:	A composite nickel-phosphorus alloy plated metal sheet excellent in strippability and having a Vickers hardness of at least 500 Hv, which comprises: a composite nickel-phosphorus alloy plating layer as a lower layer (3), formed on at least one surface of a metal sheet (2), in which Ni3P particles and fluorocarbon polymer particles (4) are uniformly dispersed; and a fluorocarbon polymer layer (5) as an upper layer formed by melting the fluorocarbon polymer particles which are exposed on the surface of the composite nickel-phosphorus alloy plating layer as the lower layer. The sum of a phosphorus content in the composite nickel-phosphorus alloy plating layer as the lower layer and a phosphorus content in the Ni3P particles is from 1 to 15 wt.% relative to the composite nickel-phosphorus alloy plating layer as the lower layer, and a content of the fluorocarbon polymer particles in the composite nickel-phosphorus alloy plating layer as the lower layer is from 0.3 to 15.2 wt.% relative to the composite nickel-phosphorus alloy plating layer as the lower layer.
