  • Patent number: 8425834
    Abstract: Provided are a method for producing a clad material, and a clad material which can prevent a brazing filler metal layer from having a higher melting point so as to prevent the strength degradation and thermal deformation of a metal material, which can reduce production costs, which can reduce in thickness the layer to prevent sagging of the brazing filler metal upon brazing and which can improve press formability. A powder press-fixing machine is used to press-fix metal powder to surfaces of a base material uncoiled from a coil by an uncoiler. In order to provide a required composition of brazing filler metal, at least two kinds of metal powder is mixed, the mixed powder being press-fixed to the base material to form the brazing filler metal layer, the brazing filler metal constituting the layer having the composition such that copper is added with at least phosphor to lower a melting point of the same relative to that of copper, thus producing the clad material.

A powder press-fixing machine 12 is used to press-fix metal powder to surfaces of a base material 1 uncoiled from a coil 2 by an uncoiler 3. In order to provide a required composition of brazing filler metal, at least two kinds of metal powder is mixed, the mixed powder being press-fixed to the base material 1 to form the brazing filler metal layer 11, the brazing filler metal constituting the layer 11 having the composition such that copper is added with at least phosphor to lower a melting point of the same relative to that of copper, thus producing the clad material 8.
