CLAD MATERIAL AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a clad material which inhibits higher melting point of a filler metal composition layer to avoid lowering of strength and generation of thermal deformation of a metallic material, which reduces manufacturing cost, which thins a filler metal composition layer to prevent the filler metal from sagging during brazing, and which further improves machinability such as press formability, and also to provide a method of manufacturing the clad material. SOLUTION: Phosphorus copper alloy powder is stuck by pressing to a base material 1 to form a filler metal composition layer 11, and the clad material 8 in which the filler metal composition layer 11 is formed is heated for a required time at a temperature at least equal to or higher than the solidus temperature of the phosphorus copper alloy and lower than the liquidus temperature. Thus, in the phosphorus copper alloy (Cu3P phase) containing 5% or more phosphorus component in weight ratio, there is formed the filler metal composition layer 11 in which copper (αphase) containing 2% or less phosphorus component in weight ratio is dispersed in a dotted manner.
